This product is a humidity sensor module HR202 very useful to measure humidity in a room with a very good accuracy, namely 5% RH. The sensor has a very low response time of up to 10 seconds, which makes it useful to collect real-time data.

The module contains two LEDs, one to indicate the presence of the power supply, and the other to indicate the logic output value.

With this product you can design innovative electronics projects using Arduino development pads. For example, with the help of other sensors you can build a smart greenhouse.
