Arduino solid state relay board.
Relay spdt sealed.
I powered the dht22 with the arduino 5 volt output.
The solid state relay can be controlled with 3v so is suitable for the 3 3v arduino boards.
However it takes about 12ma to switch the solid state relay so do check that your board can supply that amount of current from a digital output.
Led indicator for each relay.
Sparkfun qwiic quad solid state relay kit.
Some 3 3v boards like linkit one will only supply 3ma from a digital output.
For ssr solid state relay i used the digital pin 7.
Project circuit is simple connect the dht22 digital pin with the digital pin 2 of arduino.
