Industrial Leaf Wetness and Temperature Sensor _HA_WAVE There is also a 3V

There is also a 3V regulator to provide clean power to the chip and the display

This is the Adafruit Feather M0 RFM69 Packet Radio (433 MHz)

it is an ideal choice for low-power projects

They are third-party tested for the equivalent of 10+ years of UV exposure in addition to thermal cycling

we tried out PJRC's PS2_Keyboard library with great success - just check the 'simple text' example for which pins you can connect to on your 'duino (on an Uno we used digital pins 2 and 3)

Industrial Leaf Wetness and Temperature Sensor _HA_WAVE There is also a 3VThe Leaf Wetness and Temperature Sensor tracks moisture and heat on plant surfaces to help farmers prevent disease and control irrigation timing. Leaf wetness is an important indicator of the infection of pathogens on the leaves. The amount of moisture on the leaf surface makes it easy to be infected by fungal and bacterial diseases. It is used for monitoring leaf moisture for agricultural purposes, such as fungus and disease control, for control of
