Building sensors with ESP32 board is quite cost-effective ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...

All you need is an ESP32 board and some tinkering with ESPHome.

With relative capacitance measurement, instead of calculating the absolute capacitance, two additional reference capacitors are used and their raw counts along with the raw counts obtained for sensor ...

The P14 202 capacitive humidity sensor has been added to the company’s line of thin-film sensors. Measuring 1.85 by 1.85 mm, it is capable of measuring from 0 percent to 100 percent relative humidity ...

Some sensors output a processed analog signal that is linear with respect to the physical quantity being measured. Some perform quantization as well and provide a digital output. Though it is easy to ...
