The PCap01-HUM offers a platform to immediately get started in humidity measurement with the  PCap01. The system is based on the PCap01AK, Firmware version V0101 and provides a complete temperature and humidity measurement system on a small 17 mm x 8 mm PCB.

 

PCap01-HUM-DEMO

According to its modular design the humidity module is connected to a base board via I²C. This base board is battery powered and offers an LC-Display, a capacitive switch (also controlled by the PCap01) to select between temperature and humidity display,  a jumper to measure the modules current consumption and an LED that indicates an alarm level.

 

PCap01-HUM-EVA

The evaluation kit allows a full investingation of the humidity module. The module is connect through the PICOPRG to a PC. It can be fully controlled by a comfortable software and data can be numericall and graphically analysed.
