HYT939 is a digital humidity sensor which works on I2C communication protocol. Humidity is a pivotal parameter when it comes to medical systems and laboratories. So, in order to accomplish these goals, we tried to interface HYT939 with Raspberry Pi. In this tutorial, the interfacing of the HYT939 sensor module with Raspberry Pi is demonstrated and its programming using Java language has also been illustrated.
To read the humidity values, we have used Raspberry Pi with an I2C adapter. This I2C adapter makes the connection to the sensor module easy and more reliable.
Step 1: Hardware Required
Hardware that is required to accomplish the task is as follows:
2. Raspberry Pi
