Humidity/Rain Detection Sensor Module (Black)

Description:

The Humidity/Rain Detection Sensor Module (Black) can monitor various weather conditions and convert to digital signals and AO output.

Connected to the 5V power supply, the power indicator light is on when there is no water droplet on the sensor board, the DO output is high level, the switch indicator light is off, a drop of water is dropped, the DO output is low level, and the switch indicator light is on.

Features: 

• The sensor adopts high-quality FR-04 double-sided material with a large area and is treated with the nickel-plated surface, which has superior performance against oxidation, electrical conductivity and life;
• the comparator output, the signal is clean, the waveform is sound, the driving ability is strong, more than 15mA.
• With potentiometer adjustment sensitivity.
• working voltage 3.3V-5V
• Output form: digital switch output (0 and 1) and analogue AO voltage output.
• with fixed bolt holes for easy installation 7, small board PCB size: 3.2cm x 1.4cm 8, using a wide voltage LM393 comparator

Package included: 1 x Rain Sensor 1 x Rain Module (black) 2 x Dupont Cables
