Air monitoring with ESP8266 D1 Mini and sensors

Monitor garden sheds with micro controllers and sensors

Garden sheds in particular often contain many substances that you want to be notified of if a critical situation arises. This project aims to send an early notification to the owner By monitoring the air.

The following products of the project are included in the Basic Bundle:

• D1 Mini NodeMcu with ESP8266-12F WLAN module
• DHT22 AM2302 temperature and humidity sensor with circuit board (this saves you the additional resistor otherwise required with the DHT22)
• MQ-2 Gas sensor Smoke sensor Air quality module

The following products are also included in the standard set:

• Mini breadboard 400 pin with 4 busbars
• Jumper wire set M2M/F2M/F2F
• Resistor kit (resistor 470 kOhm)
• Battery shield for lithium batteries for D1 Mini

With the Standard Set you receive (together with the products D1 Mini, DHT22, MQ-2 Sensor) additional basic products that you may need for the project.

And the Extension Bundle also includes these modules:

• D1 Board NodeMCU ESP8266MOD-12F WiFi WLAN Module
• HD44780 1602 LCD module Display 2x16 characters
• LED light emitting diode assortment
• Active buzzer

With the Extension Bundle you receive the products to be notified automatically when air values are exceeded. The procedure for this is described in part 3 of the blog series. The products from the other two sets are of course also included here.
