€15-60 EUR

Paid on delivery
I want to measure the weight using a load cell sensor, connected to ESP32 through a specific circuit. Load cell sensor details: - 0-20Kg. - 4 cables: Red (excitation+); Black (excitation -); Green (signal +); White(signal -) - excitation voltage 5-15V (we will use 12V) - precission 2mV/V I have all equipment: HX711, Load cell and ESP32. Any other components can be acquired. I need a PCB with the functional circuit. First we will test with commercial boards to ensure the circuit is working and provide enough precission. Test will be done using Arduino. Please, check the attached files.
