Chirp is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant.
Chirp uses capacitive humidity sensing technique that does not interfere with the soil and does not cause corrosion of electrodes unlike resistive sensing.
Special care has been taken not to make it yet another source of annoyance - Chirp can detect if it’s day or night by measuring the amount of ambient light and will not make noise at night.
The alarm level can be set for each plant individually. As water is consumed by the plant, Chirp will detect the low moisture level and will start to emit rare short chirps. As more water evaporates, Chirp will increase the alarm rate.
Note: Chirp needs a 3V CR2032 lithium coin cell battery to work. The battery is not included. Don't forget to order one with the sensor together.
