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 ...

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 ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

There are many good reasons for growers to use some form of soil moisture-sensing technology to monitor conditions and how the water is being used in irrigated crops. First and foremost, it can make ...

Yongkun, Madhur, and Anupam's work on biodegradable soil moisture sensors was published in ACS Sustainable Chemistry and Engineering! This research was carried out in collaboration with Raj Khosla's ...

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 ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
