In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

Objective To create an efficient water level monitoring system using an HC-SR04 sensor and Arduino, enabling real-time data collection, visualization, and potential IoT integration for various ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

The XBee can detect the water level by testing for a closed circuit between the two electrodes of any sensor module. The water acts as a sort of switch that closes the circuit. When the water gets ...

The noninverting input (pin 2) is connected to sensor B through R1 for lower-level detection of the water. The open collector of the built-in transistor (pin 7) is connected to the +12-V terminal.
