Low-Power LoRa Environmental Gateway
Build a 2-Year Battery Solar-Powered LoRa Environmental Gateway with Arduino Portenta C33
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy a self-sufficient wireless sensor node that wakes every 15 minutes, reads temperature, humidity, and atmospheric pressure, transmits data over LoRa, and returns to a 10µA deep sleep. This solar-recharged gateway can operate unattended for up to two years, making it ideal for agricultural field monitoring, weather stations on remote campuses, or smart city air quality mapping. You’ll gain hands-on experience with the Arduino Portenta C33’s advanced power management and machine learning-capable microcontroller.
What You’ll Build
A complete weatherproof LoRa transmitter with integrated solar charging. The finished unit mounts inside the included waterproof enclosure and reports environmental data to any LoRa receiver—whether a second Portenta gateway, a LoRaWAN network server, or an ESP32 base station. You’ll have a field-ready device that can be left outdoors for months without maintenance.
What You’ll Learn
- Configure the Portenta C33’s ultra-low power deep-sleep modes to achieve sub-10µA quiescent current
- Interface DHT22 and BMP280 sensors over I2C and one-wire protocols
- Design an efficient solar charging circuit using the TP4056 module and 18650 lithium cells
- Set up LoRa packet transmission with the RA-02 module and implement basic error checking

Who This Kit Is For
Ideal for B.Tech ECE/EEE final-year projects requiring low-power IoT, IIT/NIT research scholars prototyping environmental sensor networks, professionals in agritech startups building remote monitoring solutions, and makers preparing for Smart India Hackathon challenges on sustainable farming or disaster warning systems. If you’ve already built basic Arduino projects and want to master advanced power optimization, this kit delivers a complete, real-world system.
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?
Every kit includes a QR code that opens our AI build companion, trained on this exact LoRa gateway project. It provides step-by-step debugging, schematic checks, and code explanations. If you need human support, our team is reachable via WhatsApp at the number printed on the box.
Can this gateway be deployed in remote agricultural fields?
Yes, the waterproof enclosure, solar panel, and 2-year battery life are designed for unattended outdoor operation. Use the LoRa data to monitor soil microclimates or track weather trends across large farms, with line-of-sight ranges up to several kilometres.
How do I receive and visualise the sensor data?
The kit is a transmitter node; you’ll need a LoRa receiver—such as a second Portenta board, an ESP32 with RA-02, or a LoRaWAN gateway—to capture packets and push them to a cloud dashboard like ThingSpeak or a local Python script. Our AI companion provides example receiving code.
Can I add more sensors like soil moisture or wind speed?
The Portenta C33 has plenty of I/O and I2C pins. You can expand the design with analog or digital sensors, but be mindful of the deep-sleep current budget. Our support can guide you on maintaining the ultra-low power profile when adding components.
C33 deep-sleep node wakes every 15 min, reads sensors, transmits LoRa and returns to 10µA sleep. 2-year battery life.
