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.
5V relay module for Arduino and other microcontroller projects
This module has 4 x 5V changover relays with the option of using them through optocouplers. There is an LED for each relay to indicate when it has been activated.
The relay allows the low current microprocessor outputs to switch higher currents and voltages. With the optocouplers it fully isolates the live side of the relays from your microprocessor, this will require a seperate 5V supply to power the relays.
Trigger voltage : 5VDC
Supply Voltage : 5VDC (only needed if using optoisolators)
AC Switch ratings : 250V 10A
DC Switch ratings : 30V 10A
