MAITECH LARGE AREA RAINDROP MODULE / RAINDROP SENSOR - BLACK IN SOUTH AFRICA

Description Voltage: 5V Power indicator：Output signal LED indicator. TTL-level output, TTL output valid signal is low. Driving capacity of around 100mA, can directly drive relays, buzzer, small fan, and so on. Sensitivity can be adjusted via a potentiometer. LED lights up when there is no rain output is high, raindrops up, ground level output, LED lights. Raindrops and control panels are separate, easy to line leads. Large raindrops board, more conducive detected rain. Board with positioning holes to facilitate installation Dashboard board size: 3 x 1.6mm Large area raindrop detection plate 5.4 x 4.0mm Use When connected to a 5V supply power lights, no water droplets on-board sensors, DO output is high, switch lights off, drop a drop of water, DO output is low, the switch indicator light. Brush above water droplets, has 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.   General Brand MaiTech Quantity 1 set Form Color Black Material Glass fiber + plastic + iron Specification English Manual / Spec No Other Features Certification NO Dimensions & Weight Dimensions 2.17 in x 1.54 in x 0.12 in (5.5 cm x 3.9 cm x 0.3 cm) Weight 0.46 oz (13 g) Packing List 1 x Raindrop sensor board 1 x Dashboard 5 x DuPont line (21cm)
