It operates with low power consumption, requiring only approximately 2.5 µA when using a 1 MHz transducer at one measurement per second for metrology. The design also allows flexibility to test different pipes and transducers, supporting direct interfacing with a pair of transducers. Users can ea...
The device consists of an Arduino hooked up to a cheap flow meter sourced from Banggood. The sensor consists of a paddle wheel that sits in the water flow, fitted with a magnet. A hall effect sensor picks up pulses as the magnet spins, and counting these allows the flow rate to be me...
Naturally, SoC boards scored the highest in terms of processing power, and are lacking in low-level interfacing capabilities when compared to MCU-based counterparts. The Raspberry Pi 4B shows the highest processing score and an average interfacing score, whereas the ESP32 was found to be the ...
