Tire pressure sensors are a key part of ensuring drivers stay informed about the condition of this crucial piece of automotive equipment.

[imsolidstate] built his own pressure sensitive mat. It utilizes two discs of copper clad board with a piece of foam in between for each of 64 sensors. As the foam gets compressed, the capacitance … ...

Then he sets up the sensor and all the desired actions in ESPHome. Of course, with an ESP32, it’s easy to add a second pressure mat for [Mrs. The Home Automation Guy]’s side of the bed.

The idea of using the piezoelectric effect to make pressure sensors is not new, says Toh-Ming Lu, a professor of applied physics at Rensselaer Polytechnic Institute (RPI). “What’s interesting ...

This article explains how to use the Piezoresistive Effect and Measure Pressure from First Sensor.

1. Measurement of pressure with silicon sensor dies is based on the piezoresistive effect, which is mechanical stress that results from a pressure difference across the diaphragm.
