Getting started with 5o kg Body load cell
In this tutorial we are going to see how to connect the 5o kg load cell to the arduino uno using the hx711 so that we can read the weight of an object which is less than 5o kg, let’s start
Step1: Hardware required
Step2: connecting the hardware
connect the hardware as shown on the image below make sure that the connection are ok before uploading the sketch
Step3: Making the sketch and test the circuit
before uploading the sample sketch you need to have the HX711 library if not download it here. and the sample sketch you can download it from here. this sample sketch has auto calibration and manual calibration which means that the beginning of the sketch the auto calibration will occur and after you can make manual one. upload the sketch to the arduino after open your serial monitor and you will start getting values if you put on the load you will get it’s weight in Kilograms
