With this system, you can be able to monitor your garden such as soil moisture, temperature, humidity and of course you can control the water pump for irigation with telegram chat application. It use ESP8266 12E for controller, DHT11 for temperature and humidity sensor, and Capacitive soil moisture sensor. You can program this project by arduino software with ESP8266 core in it.

Part list :

• ESP8266

• DHT11

• 5V Relay

• 5V Buzzer

• PC817

• 3mm LED

• AMS1117 3V3

• Transistor 3904

• Tactile button

• Capacitor 10uF/16V

• Terminal Block

• Soil moisture sensor

• Resistor 680, 4k7

Before you assembly it, you have to program it first by arduino software. You must have ESP8266 core in your arduino software to be able programming the esp8266 chip.

ESP8266 can be programmed by usb ttl.

you have to setting telegram bot at the first to get the api key bot. and the copy that api to arduino sketch.
