M15 Sensor Design
Sensor Design
Creating affordable and efficient sensors is important for the success of our monitoring platform. We will develop sensors using the ESP32 microcontroller, which is both cost-effective and powerful.
Key Components
Microcontroller
ESP32: A low-cost, low-power system on a chip (SoC) with integrated Wi-Fi and dual-mode Bluetooth. It is suitable for IoT applications due to its versatility and performance.
Sensor Modules
DHT22: For measuring temperature and humidity.
MQ-135: For monitoring air quality.
BMP180: For atmospheric pressure and temperature.
Connectivity
PubSubClient Library: An MQTT client for the ESP32 to facilitate data transmission to the MQTT broker.
Enclosures
Custom 3D Printed Enclosures: We will use high-temperature tolerant PETG material to develop enclosures that protect the sensors from harsh environmental conditions. These enclosures will be designed and manufactured in Lahore.
Sensor Assembly
Microcontroller Setup:
Program the ESP32 using the Arduino IDE.
Install and configure the PubSubClient library for MQTT communication.
Sensor Integration:
Connect the DHT22, MQ-135, and BMP180 sensors to the ESP32.
Ensure all sensors are correctly calibrated and provide accurate readings.
Enclosure Design:
Design 3D models for the enclosures using CAD software.
Print the enclosures using PETG material to ensure durability and heat resistance.
Deployment:
Assemble the sensors and microcontroller into the enclosures.
Deploy the sensors in various locations across Lahore to start collecting data.
By developing these custom sensors, we can significantly reduce costs and increase the deployment scale of our monitoring network.
