Understanding when and why sensor calibration matters for accurate data.

Two primary types of soil moisture sensors are commonly employed: metal prong sensors and PCB probe sensors. Each approach offers distinct..

Knowing how to interpret sensor readings is more important than the sensor itself.

Imagine you've developed a versatile datalogger-controller using an Arduino board to monitor and control environmental conditions. This device can accept signals from a variety of sensors, including soil moisture, electrical conductivity, and pH sensors, and can control solenoid valves using a relay board. To add a layer of precision, the datalogger incorporates a GPS module to geotag sensor data during field installations.

Signal processing includes steps such as baseline calculation, feature extraction, and normalization. These steps consider user settings ...
