Hello, and happy new year!
I have got a soil humidity sensor with digital output for my tomato plant in the cellar, a 12V Delay Timer Monostable Switch Adjustable Relay Module NE555 Car Oscillator, and a pump driven from a 12 v battery charger. I would like a cirquit to sense the sensor high or low say 2 times a day, and send a pulse to the delay timer to start the pump for a set seconds when required. I am not an experienced electronic engineer!
