Mini Liquid Level Sensor is designed to be inserted vertically into wet environments to detect liquid level from 0 to 1.88” (48mm) or as an alarm. The 28090 sensor has a single analog output which may be directly connected to the Propeller Activity Board 4-channel A/D converter or easily interfaced with the MCP3002 A/D with a FLiP Multicore Microcontroller. The 28090 mini liquid level sensor is ideal for water level alarms for moisture-sensitive environments, water level indicator for fluid reservoirs, and stream-level indicator when used in a controlled reservoir (stream well).
The sensor is used for determining the liquid’s level in the vessel. It is powered with the voltage from 2.0 V to 5.0 V. The output is an analogue voltage that increases its value along with the depth of immersion of the probe which makes it compatible with most of the development kits, for example, Arduino. The device works in the range of up to 48 mm.Featured By RoboticsBD.
