High Sensitivity Water Sensor Switch for Arduino Red
- High Sensitivity Water Sensor for Arduino UNO MEGA R3 Mega2560 SainSmart.
- 1 Piece.
Judge the water level through with a series of exposed parallel wires stitch to measure the water droplet/water sizeEasily change the water size to analog signal, output analog value can directly be used in the program function, then to achieve the function of water level alarm.Low power consumption, high sensitivity, which are the biggest characteristics of this mdoule.Compatible with Arduino UNO, Arduino mega2560, Arduino ADK etc.water sensor brick is designed for water detection, which can be widely used in sensing the rainfall, water level, even the liquate leakagethe brick is mainly comprised of three parts: an electronic brick connector, a 1 mohm resistor, several lines of bare conducting wiresthis sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sens tracesthe sensor traces have a weak pull-up resistor of 1 mohmthe resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace believe it or not this circuit will work with the digital i/o pins of your arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces features : working voltage: 5vworking current: <20mainterface: analogwidth of detection: 40mm x 16mmworking temperature: 10c-30cweight: 3gsize: 65mm x 20mm x 8mmarduino compatible interfacelow power consumptionhigh sensitivityoutput voltage signal: 0~4.2vpin definition : "s" stand for signal input"+" stand for power supply"-" stand for gndapplications : rainfall detectingliquid leakagetank overflow detector.
