The EzloPi smart devices provide automation through simple, customizable use with our open-source EzloPi platform, making daily life easier and improving human-machine interactions.
Before moving into this example, it is very important to know about the device registration, provisioning and converting the ESP32 device into an EzloPi device along with knowledge of Web Flasher, MiOS Mobile Application for Android/iOS and the MiOS Web Application.
In this project, we will see how to interface an MQ135 gas sensor with an EzloPi device to monitor indoor air quality.
The MQ135 NH3 gas sensor, when integrated with the EzloPi device, provides an efficient and reliable solution for monitoring ammonia (NH3) levels to protect your environment from potential hazards and bringing safety and environmental awareness to the forefront of your IoT projects. This powerful combination makes it ideal for applications such as indoor air quality management, industrial safety, and environmental monitoring.
The following components are required for interfacing with the EzloPi device:
The wiring diagram for the ESP32 30 pin is represented as below:
The following connections are made in order to complete the circuit setup.
From ESP32 to the MQ135 Gas Sensor module:
1. Set up your device/hardware by visiting https://config.ezlopi.com/
Now, select COM Port to which your ESP32 device is connected. In our case, the COM3 port is used.
You can download the MIOS Android app from the Google Play Store and Apple App Store.
