[wpdm_package id='17101'] TSL2561 Sensor Pinout This module has 2 pins: VCC: Module power supply - 5V GND: Ground  SLC: I2C clock  SDA: I2C ...

Rain Drop Sensor Features The raindrop sensor module is used for rain detection. The module includes two parts. The first part is a printed circuit board that has a network of copper paths. When rain drops fall on this board, some parts of copper paths are connected to each other and the overall resistance of the board is reduced. The second part is a board converting analog output to digital output. The sensitivity of the sensor can be adjusted using the potentiometer on the board. Tip The raindrop sensor...

IR Flame Sensor Features The flame sensor is actually an infrared receiver. In this module, the output of the infrared receiver is measured using a comparator IC. If the fire and flame (or any other infrared source) is close to the sensor, the output of the comparator is LOW, otherwise the output is HIGH. Note There is a potentiometer on board to change the sensor's sensitivity. In practice, this potentiometer changes the reference voltage of the comparator IC (the same voltage that the sensor voltage is co...
