12v Relay Module Soil Moisture Soil Moisture Sensor Robot Switch on Off A8

Description

Package Contains 1 Piece – Relay module soil moisture senser Description of a
baby This is a simple water sensor can be used to detect the moisture of the
soil, when the soil water deficit, the relay is switched off, and vice versa
relay. Use this sensor produced an automatic watering device, so that the
plants in your garden need not to manage. 2 adjustable sensitivity (blue
digital potentiometer adjustment) 4 Operating voltage 3.3V-5V 5 relay output,
more convenient to control. 6 with fixed bolt hole for easy installation 7

module is most sensitive to environmental humidity is generally used to detect
the moisture content of the soil. 2 module in the soil moisture of less than
the set threshold value, the status of the relays in a disconnected state, the
output performance: normally open and public open, normally closed, and public
conduction; exceeds the threshold value is set when the soil moisture relay
state absorption and status, the performance of the output: normally open with
the public on pass, normally closed and public disconnect according to this
principle embedded in the own system. Relay wiring parameters: AC voltage
250V, AC current maximum 10A maximum 30V DC voltage, DC current up to 10A
