How to Read Temperature and Humidity with SensiEDGE || SensiBLE

The STMICROELECTRONICS HTS221 Capacitive digital sensor for relative humidity and temperature Integrated inside SensiEDGE || SensiBLE.

What is HTS221 ?

The HTS221 is an ultra-compact sensor for relative humidity and temperature. It includes a sensing element and a mixed signal ASIC to provide the measurement information through digital serial interfaces.

The sensing element consists of a polymer dielectric planar capacitor structure capable of detecting relative humidity variations and is manufactured using a dedicated ST process.

The HTS221 is available in a small top-holed cap land grid array (HLGA) package guaranteed to operate over a temperature range from -40 °C to +120 °C.

What is SensiEDGE || SensiBLE ?

The SensiBLE “IoT Hardware Ready” allows quick and easy prototyping of IoT devices. It just works — connect your sensor solution to the cloud less than three minutes.

Step by Step how to connect SensiEDGE’s SensiBLE to IBM Watson IoT Platform in IBM Bluemix and watch live sensor data stream.

Step by Step how to read Temperature and Humidity

1. Before we start you need to have a physical IoT hardware.

Please order: SIMBA-PRO from Arrow, Mouser or RS-Components

2. Download & Install ST BLUEMS from Google drive / App Store

Reading using App:

Reading using PLOT

Temperature and Humidity Measurement using IBM Cloud.

3. Navigate to the last page on the app.

On the Device id, write name of the Device. This name will be your identifier in the IBM cloud.

Press cloud

4. on/off the sensors you want to see on the cloud

5. Open Browser :

Enter the name of the module as you call it on step 2.

6. press the sensor you want to see:
