AVT1483 A

The signaling device is designed mainly for monitoring the soil moisture of plants grown in pots. The basis of its operation is the fact that water is a good guide. This means that the moist soil conducts well and the drying one becomes an insulator. Earth resistance is measured using a pair of pointed electrodes that are placed in a pot. The measurement takes place continuously and when the soil dries up, the system triggers sound signaling that reminds of the 'desire' of plants.

The device is especially recommended to all lovers of pot plants

Selected parameters:

• humidity sensor - two electrodes hammered into the ground
• the possibility of smooth adjustment of the sensitivity of operation, i.e. the minimum humidity level
• sound signaling
• small dimensions
• power supply - 3 Vdc (lithium battery)
• tile dimensions 52x33mm
