Discover the capabilities of the ZMPT101B voltage sensor and learn how to interface it with Arduino for precise AC voltage measurement. This voltage transformer module allows you to measure AC voltages up to 250 volts with analog output. As the input voltage changes, the output voltage of the sensor adjusts accordingly. What is ZMPT101B Voltage Sensor? The ZMPT101B is a voltage transformer used to measure AC voltage. You can measure AC voltages up to 250 volts by using this module. The output of th...

DS18B20 Temperature Sensor Features The DS18B20 is a temperature sensor that can measure temperature in the range of -55°C to + 125°C with an accuracy of 0.5 ° C. The output accuracy of this sensor is adjustable from 9 to 12 bits which is set to 12 bits by default. The communication protocol of the this sensor is single-wire, and to measure the ambient temperature  you only need to connect one wire to Arduino. Note One of the biggest advantages of this sensor is its one-wire communication protocol....

Photoresistor Sensor Features Photoresistor is a kind of resistor that is sensitive to light. The resistance value changes by change of light intensity. As the ambient light increases, the photoresistor resistance decreases and with decreasing light, the resistance increases. The output characteristic of this sensor is nonlinear.

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...
