Description
As a part of the question yesterday that has been complained on its feasibility, I have successfully made a pump control for watering my root-top garden. Input: Control a pump using blynk app and ESP8266-01S hardware with following requirements:
- Temperature sensor with DS18b20
- Raindrop sensor: to stop/delay the pump from watering the garden when rain happened for more than 30 minutes and also keep the pump from longer operation if daily temperature is too high.
- Waterflow detector: to prevent problem to pump Design: The schematic is simple, just need a 5V power module(I used a mobile charger 700mA) and a single relay with ESP8266-01S module, ds18b20, water-flow switch, raindrop sensor, few headers and resistors. See my sketch as below
