Overview:
The water level (level) sensor is an easy-to-use, compact and lightweight water level / water droplet recognition detection sensor. The sensor measures its water droplets through a series of exposed parallel wire traces. The amount of water makes the analog signal output by the sensor change accordingly , So as to determine the water level, and easily complete the conversion of water volume to analog signals.
Specifications:
Specifications:
Power supply voltage: 3.3V-5V
Working current: <20mA
Working temperature: 0-60 ℃
Interface definition: XH2.54 (3pin: GND, VCC, Singal)
Communication signal: analog signal output
Size: 20.4 * 66mm
Note: The exposed wire part of the water level sensor can be immersed in water, but the signal processing part next to the interface cannot touch the water, which may cause a short circuit on the control board. Therefore, when using it, you need to be careful not to measure the liquid level that exceeds the sensor water level line.
Applications:
Using the characteristics of the water level sensor, you can cooperate with microbit to make a simple water level monitoring device. The output analog value can be directly applied by the program to achieve the effect of water level alarm, low power consumption and high sensitivity.
