Fog Harvesting Monitor
Build a Fog Harvesting Monitor System with Arduino – Measure Water Yield in Real-Time
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Fog harvesting is a vital source of water in arid regions, but quantifying yield remains a challenge. This kit lets you build a monitoring station that continuously records the weight of collected water on a mesh, correlating it with humidity, temperature, and atmospheric pressure data from DHT22 and BMP280 sensors, all timestamped by a DS3231 real-time clock. Whether you’re an engineering student prototyping a smart agriculture solution or a researcher validating fog collection efficiency, this project delivers lab-grade data logging in a field-ready package.
What You'll Build
A complete data acquisition system that measures water weight using a sensitive load cell and HX711 amplifier, reads microclimate data with DHT22 and BMP280, logs everything to an SD card, and displays real-time readings on an OLED screen. With the DS3231 RTC, every data point carries an accurate timestamp, enabling long-term analysis of fog harvesting performance under varying weather conditions.
What You'll Learn
- Calibrate and interface a 1kg load cell with HX711 for precision weight measurement
- Read and fuse data from DHT22 and BMP280 sensors to understand environmental impact on water yield
- Implement time-stamped data logging to microSD using an RTC for field experiments
- Design and test a complete standalone environmental monitoring device on a prototype PCB

Who This Kit Is For
This advanced kit is ideal for BTech (ECE/EEE/Mechanical) students working on environmental monitoring capstone projects, participants of Smart India Hackathon tackling water scarcity themes, and researchers at IIT/NIT/VIT/BITS Pilani validating fog harvesting models. It’s also suitable for CBSE Class 12 students aspiring for advanced STEM coursework, provided they have prior Arduino experience.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code in the kit to access our AI companion trained on this exact project; it can debug code and wiring step-by-step. If you need human help, just send a photo on WhatsApp and a Compoden engineer will respond within a few hours.
Can this kit be used for real field deployment?
Yes, with a 9V battery and a weatherproof enclosure (not included) it can run for hours. For longer deployments, add a solar panel power management module.
Does it include the fog harvesting mesh?
The kit provides only the monitoring electronics. Use any standard mesh material like polypropylene; a 30cm x 30cm piece fits the load cell platform perfectly.
Can I modify the code to send data to the cloud?
Absolutely. The Arduino Uno doesn’t have built-in Wi-Fi, but you can add an ESP8266 module to upload data to platforms like ThingSpeak or Blynk using the same I2C and UART lines.
Load cell measures mesh water collection weight over time correlated with humidity and temperature from DHT22 and BMP280.
