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 ...

Makers might be interested to know that Adafruit is now stocking a new STEMMA capacitive soil moisture sensor which provides superior enhancements when compared with resistive style soil moisture ...

A frequent beginner project involves measuring soil moisture levels by measuring its resistance with a couple of electrodes. These electrodes are available ready-made as PCBs, but suffer badly from ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

Soil moisture measurement is fundamental to understanding hydrological processes, crop water dynamics, and broader environmental monitoring. Recent advancements have driven the development of ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...
