By counting the pulses from the output of the sensor, we can easily calculate the water flow rate (in litre/hour – L/hr) using a suitable conversion formula. The Arduino Sketch (code) uses the ...

The I2C bus or TWI (Two Wire Interface) allows a single master IC to share communication lines with multiple slave ICs. In our case Arduino is the master and 3 x TC74 sensors are the slaves. As you ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display ...
