Micro Load Cell (Weight Sensor) with 5kg Capacity ESP32 Series These are Metal Film ResistorThis straight bar load cell (also known as a strain gauge) can convert pressure (force) of up to 5kg into an electrical signal. Each load cell can detect variations in electrical resistance that changes in response to, and proportionality with, the strain (for example, pressure or force) applied to the bar. You can use this gauge to determine how heavy an object is, if the weight of an object changes over time, or if you just need to detect the
