Soil Hygrometer module for Arduino
Soil hygrometer module with digital and analogue outputs for Arduino and other microcontroller projects
This module has a seperate 2 pronged moisture detector that is inserted into the soil and then connected to the comparitor board using the supplied link wires. It can give out a digital (High/Low) signal at a certain moisture level that can be set by adjusting the potentiometer on the board. There is also an analogue output to give you a more precise reading of the moisture level in the soil.
Voltage : 3.3 to 5VDC
Comparitor PCB Size 30x16mm

Non-Contact Metal Detector Kit
Basic metal detector sensor module with buzzer and LED alarm. Will detect metal at a range of up to 60mm, including through soil, cothing, etc. Requires an input voltage of 3-5V DC, which can be supplied to the module via the 2 pin screw terminal (e.g. battery pack, USB, power supply). The sensitivity can be adjusted by the VR1 potentiometer.
