Force Pressure Sensor for measuring lab waste
This force pressure sensor will use inputs from four force sensor resistors to measure the weight of a waste bin in my laboratory. When the bin is 60% full (36 lb), the Arduino will send a message to me to empty the contents. The digital read out will display the weigh and status of the bin.
This project is constructed out of HDPE plastic and has rubber feet to elevate it off the floor. The Arduino and LCD screen are protected inside the perimeter of the forcemeter frame in a cutout with clear acrylic plastic adding additional protection.
