Pumcontroller

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:

1. Temperature sensor with DS18b20
2. 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.
3. 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
