DIY Raindrop Sensor + HL-01 Module w/ Jumper Wire for Arduino
Production: - High quality FR-04 dual sided material£¬ ultra area 5.0 x 4.0cm. Nickel-plated surface£¬ with antioxidant£¬ electrical conductivity£¬ and superior lifetime performance - Comparator output£¬ clear signal£¬ and nice waves£¬ powerful driver over 15mA - Equipped with potentiometer to adjust the sensitivity - Working voltage: 3.3V~5V - Output method: Digital switch output (0 / 1) and analog AO voltage output - Easy installation with fixed screw hole - PCB size: 3.2cm x 1.4cm - Uses wide voltage and LM393 comparator Features: - When connected to a 5V supply power lights£¬ no water droplets on sensor board £¬ DO output is high; Switch lights off£¬ drop a drop of water£¬ DO output is low£¬ the switch indicator light. - Clean the water droplets£¬ returned to output high state. - AO analog output can be connected to the microcontroller AD port to detect drops in the above rainfall size. - DO TTL digital outputs can also be connected to the microcontroller to detect whether there is rain. Connection: VCC: Power positive (3~5V) GND: Power negative DO: TTL switch signal output AO: Analog signal output
