Frequently asked questions

I’m a developer. How can I be sure SensiEDGE products are right for me?


SensiEDGE products are built as “Hardware Ready” to simplify Development of IoT products. Modules include Connectivity, Sensors, Microcontroller and battery look and act like a final product, accelerating the proof of concept stage from months to weeks (and even minutes sometimes). All modules are pre-installed with a Demo that demonstrate the main functions of the product. In most cases you can reach a product demonstration stage for investors with real demo, delivering a clear vision as to how your product will look and act.




What are the main advantages of SensiEDGE IoT products ?


All our products are designed as if we wanted to build the end device. Therefore all the components are very high quality. The PCB is designed as end product not as a development kit. So when you choosing it for prototyping and developing your code for a few months, it actually delivers development continuity to your final device.
The main advantage is that you have a ready module that looks and act as final product. And if needed the SensiEDGE team will help redesign to fit your end customer final requirements.
This is a “off-the-shelf” integrated and pre-certified “Hardware Ready” module, which gives you freedom from hardware development and production logistics.




What are the main advantages of developing applications based on SensiBLE?


It’s ready and it’s working. It’s connected to both App & cloud. It looks like the end product, and it acts as final product. It delivers sensors data to Android/iOS App. In addition, there is an open source firmware and free of charge SDK for Android/iOS developers.




What are the key differences between SensiBLE and SensiBLE 2.0?


First we support our customers during their development cycle. Many of our customers initially started with SensiBLE v1.0, and eventually we have been asked to make cost performance product as well to replace the coin battery with a rechargeable battery. This resulted in SensiBLE 2.0 being created. Second difference is with the SensiBLE 2.0 form factor. It gets smaller as we use SoC that is integrating Microcontroller and BLE in one single chip (rather than using a two chip solution as with SensiBLE v1.0).




How long can the modules run from a battery ?


It is very difficult to answer as it depends on many factors. All our current product design for very low application and every electrical component is chosen first because of its best power consumption and not because it is a cheap product, so it does depend on the final application. First key factor is which sensor is used, and how many times per seconds/minutes/day. How many time and how long will the application operate BLE is another key factor; many other factors impact on the power consumption of the product. SensiBLE v1.0 and SensiBLE v2.0 can use different types of batteries that will eventually be adapted to the end product when the final application software is ready.
Perhaps a better question, from a customer standpoint, is: what’s my application and how long should the battery work? This will inform the overall design process.




Can the modules work with energy harvesting?


Yes of course! As long the energy harvesting system can generate a minimum of 2.0v.




What are the software tools required to begin Development?


Professional IDE and compiler that can be used to develop firmware are IAR and Keil. System Workbench IDE and compiler are giving a nice performance, what’s best they’re free of charge and supported by open source community. System Workbench is cross platforms so it can be used for Windows and MAC OS developers.

SensiBLE v1.0 supported by Arduino IDE.




Do I need any other hardware to begin development?


Our development kits are integrated with debugger and programmer. No extra tools are required - our development kit is all you need, along with your creativity.




What sensors are included in the module?


Accelerometer, Gyro, magnetometer, Pressure, Humidity, Light, Microphone it’s only the core sensors that included by default in every module. Some other products include additional sensors like UV sensor; please enquire with SensiEDGE and let us know your requirements.




Can I add expansion boards?


SensiBLE and SensiSUB development kits are designed to integrate with Arduino shields. Every Arduino expansion Shield will fit in nice with our SensiBLE and SensiSUB development kits.




Is there a smartphone (iOS or Android) app?


SensiBLE and SensiBLE 2.0 are equipped with BLE to communicate with smartphone App. Both platforms are also supported by App “ST BLUEMS” and many other Apps that are developed by our partners. Free of charge SDK both for iOS SDK and Android SDK is also available, so every App developer can develop his or her own app and use SensiBLE and SensiBLE 2.0 as Sensor HUB.




Can I easily connect SensiEDGE products to the Cloud?


Yes! All SensiEDGE products connect to cloud service by default. This is what gives you instant capability to start development.

Who is behind SensiEDGE?


SensiEDGE was established in 2015 by a team of people that helped build many projects for big customers and wanted to help to do so for every maker, startup and even students that simply cannot spend big money to build an electronics system. In the IoT era every idea is worth come true is the motto of Milan Yudkovich, Founder and CEO of SensiEDGE.




Are your products certified?


Certification of the product especially FCC is done by the relevant authorities only when the product is completely done in its original enclosure and final software runs on it. By following certification rules and integrating Certified Communication components, SensiEDGE products are pre-certified and required very easy certification process.




Do you offer a warranty?

How do we convert Gyro unit dps to rad/s?


To convert degrees per second to radians per second we use the following formula: rad/s = dps * PI / 180 This can be done either on MCU side or on the application side.




How much logging data of Gyro/Acc/Magnetometer can be stored before sending via BLE.


On Current version of SIMBA-PRO we using very low power serial flash 4Mbit. For example we will use 100Hz sampling rate. Gyroscope, Accelerometer, and Magnetometer have 3 x 16-bit axes each. This means one set of data takes 3 x 3 x 16 = 144 bits (18 bytes). 4Mbit flash can store 4000000 / 144 = 27000 entries. At 100 Hz frequency, it will be able to store 27700 / 100 = 277 seconds of data. (*) We should take into account that flash memories usually can handle 100000 writing cycles. After this limit, memory won't work correctly. To expand flash life, we have to reduce the number of writings to flash memory so we should have a buffer of RAM to store data temporarily before writing. The size of the buffer should be multiple of the flash memory page size. Also, to ensure that data are not corrupt, we have to use CRC which will take one or two bytes for every data block (one flash page or so).




I saw that you provide regulated +3.3V and +5V_USB (on J1). What I didn't see was how much current is available on either one of these rails.


SensiBLE doesn't provide a regulated power output. 5V pin is input for powering the board from USB. Input voltage range is 2V .. 5.5V. 3V pin is input for powering the board from a 3V supply (coin battery for example). This pin is directly connected to MCU power and the output of LDO (through the diode). Input voltage range is 1.8V .. 3.3V. In the case, when a 5V power supply is connected to 5V pin, 3V LDO output voltage will appear on this pin. Technically, you can use this pin as a power supply, but we don't recommend doing this. Using an external voltage regulator is better. In the case, if you still want to use SensiBLE LDO as a power supply, be careful - don't exceed 150mA of the load current. Use bypass capacitors. Average power consumption of SensiBLE in the most consuming mode is 12mA. Peak current is 25mA.




Can I use ADC123_14 to digitize a serial stream of voltage pulses (just an on/off sequence)? I assume it is connected to the 12 bit ADC?


ADC12_IN13 and ADC12_IN16 are available. You can use these pins for digitizing the signal. The reference voltage for ADC is 3V. In the case, you want to process a digital signal, it's better to use the digital input. Using ADC will be more difficult and less accurate.




What is the power consumption of the SensiBLE?


SensiBLE demo can work in several modes with different power consumption. The table below shows the current consumption of SensiBLE in different modes.




How calculated LUX values ?


The APDS-9250 allows to measure values for all 4 channels (Red, Green, Blue, IR). The ALS value showed in our demo is a LUX value calculated from the Green and IR channels. How it is calculated you can see on the next link: https://github.com/SensiEDGE/SensiBLE1.0/blob/master/Projects/Multi/Applications/ALLSENS/Drivers/simba_lux_apds9250.c#L118-L145.
Though the APDS-9250 store values for all 4 channels in internal registers, we don't show these values, but as our project is open sorce - you are free to implement this possibility. To get more information regarding APDS9250 see the datasheet: https://www.broadcom.com/products/optical-sensors/ambient-light-photo-sensors/apds-9250
