This load cell can measure up to 20kg of pressure (force) into an electrical signal with the help of HX711 A/D Pressure Sensor. Each load cell is able to measure the electrical resistance that changes in response to, and proportionality to, the strain (e.g. pressure or force) applied to the bar. With this gauge, you will be able to tell just how heavy an object is, if an object’s weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.
It has Four lead wires which can be connected to HX711 A/D Pressure Sensor. It is easy to use with driving voltage 5-10V and produce the output voltage as per the force changes over it.
Installation of the Sensor is also the simple task, it needs to fix one end through the screw hole and the other end left floating state, according to the label indicates the direction of the gravitational force exerted particular attention must not directly push the white plastic cover part of the sensor in order to avoid damage.
An electronic weighing machine uses a load cell to measure the load or pressure produced by the load, here most load cells follow the method of the strain gauge, Which converts the pressure (force) into an electrical signal, these load cells have four strain gauges that are hooked up in a Wheatstone bridge formation.
When we apply to load the strain gauge resistance will change and hence the output voltage from the load cell get changes by the way we can measure the load value.
