Liquid-Level Monitoring Using a Pressure Sensor – Bar-Graph Display
https://www.electronics-lab.com/project/liquid-level-monitoring-using-a-pressure-sensor-bar-graph-display/
This project allows users to monitor the liquid level on a Bar-Graph display. The liquid level is measured using a pressure sensor, the sensor is placed on top of the tank and is connected to an open-ended tube that is submerged in the water tank. The amount of water in the tank creates a proportional […]
Digital Pressure Gauge 0 to 10kPa (0 to 1.75 psi) with OLED display
https://www.electronics-lab.com/project/digital-pressure-gauge-0-to-10kpa-0-to-1-75-psi-with-oled-display/
The project presented here is a Digital Pressure Gauge using an OLED display. The measuring range of this unit is 0 to 10kPa (0 to 1.75 psi). Additional this compact open-source hardware is Arduino compatible. This board can be used for measuring low pressure up to 1.75psi with great accuracy. The board contains an MPXV5010DP […]
Liquid or Air Pressure Switch with Relay
https://www.electronics-lab.com/project/liquid-or-air-pressure-switch-with-relay/
This pressure switch project is built using a piezoresistive transducer, LM358 OPAMP as comparator, and a relay. The circuit activate the relay when the pressure in a system exceed a given set-point. Basically, this switch can power ON or OFF a pump, valve, motor, when certain pressure is reached. A trimmer potentiometer is provided to […]
