On vacations

From Refarm the city

refarm on vacations the board that let's you control your farm. it has 1 light, 1 temperature and 4 humidity sensors. it can control 3 water pumps or 3 water valves. the board comes with general code and you can change it with your personal needs. board for DIY and pre-assembled.

humidity sensor zone

start with the 100Ω resistors. they are 8 and go vertical

then apply the 2N2222 transistors

then solder the diodes. there are 5 of them. note that the diodes have polarity that means that they have a specific direction to work.

voltage regulator

apply the capacitors. note that the eletrolitic have polarity, the ceramic no

the energy socket and the 2 voltage regulators, the 7805 and the 1117

the clock

apply the crystal and the ceramic capacitors.

data info on board

solder the RGB led and his resistors. the RGB has polarity

resistors

the 3k3, 8k8 and 10k resistors.

water pump control

the 10k resistors

the TIP 120

the sockets

the atmega and radio sockets

the other sockets and voilá you are ready to put the board inside a scarecrow
