Tindie Weblog | Water Condensation Sensor Board

If you could detect rain drops, or water normally, sensors can be found which are fairly able to the duty. Nevertheless, based on Tindie vendor cowtheory, these sensors are solely good at detecting massive droplets of water, not a lot the a lot the finer layer of moisture droplets shaped by condensation. After unsuccessfully trying to find such a moisture sensor on the Web, cowtheory as a substitute got here up with the Water Condensation Sensor board, a novel gadget configured particularly for this job.

The gadget is actually a small circuit board with very skinny (.2mm) traces, permitting it to sense tiny condensation droplets. Utilizing it with a microcontroller with it’s simple sufficient; join one pin to floor and the opposite to an analog or digital pin set as a pullup enter. When condensation hits the sensor panel’s floor, it connects the traces simply sufficient to tug the pin to floor, permitting the microcontroller to detect this state and take motion as wanted.

One might see such a sensor used to detect condensation from a bathe, or maybe to see when your metallic mailbox is dry sufficient within the morning to ship out (Tindie) packages with out residual moisture. In fact there are an enormous variety of different tasks one might do with such a sensor. Maybe it should spark a brand new thought, and even revive an outdated one!
