Low-Power LoRa Environmental Gateway Pro
Low-Power LoRa Environmental Gateway Pro – Deploy a Remote Sensor Node with 2-Year Battery Life and Zero Maintenance
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a solar-powered environmental monitoring node that wakes from a 10 µA deep sleep every 15 minutes, reads temperature, humidity, and atmospheric pressure, then transmits the data over LoRa to a base station kilometres away. Designed for agricultural fields, remote weather stations, or industrial monitoring where power and connectivity are scarce, this kit eliminates the guesswork of integrating extreme low-power hardware and long-range wireless communication.
What You'll Build
A rugged, waterproof sensor node powered by four 18650 batteries and a 2W solar panel, capable of operating autonomously for up to two years. It uses the Arduino Portenta C33 to manage ultra-low power states and the SX1278 LoRa module to send sensor data up to 5 km line-of-sight. The finished unit sits inside a weatherproof enclosure, ready for pole or wall mounting in the field.
What You'll Learn
- Configure the Arduino Portenta C33’s deep sleep and wake-up timers to achieve sub‑10 µA standby current
- Interface DHT22 and BMP280 sensors over I2C and one-wire with power gating to eliminate leakage
- Optimise LoRa SX1278 transmission parameters for range and energy efficiency
- Design a solar charging circuit with TP4056 module and multi-cell 18650 pack for 24/7 operation

Who This Kit Is For
Engineers and researchers deploying long-term outdoor environmental monitoring networks, B.Tech ECE/EEE final‑year students working on LoRa‑based IoT projects for Smart India Hackathon or college symposiums, and professionals at agritech or smart city startups seeking a production‑worthy sensor node reference design. The advanced power management and RF techniques are directly applicable to IIT/NIT/VIT capstone projects and industrial prototyping.
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 on the box to access your AI build companion trained on this kit. It checks your connections, explains every step, and helps troubleshoot. For extra help, message us on WhatsApp—our team responds within hours.
Can I use a different LoRa frequency for my country?
The kit includes a 433 MHz module, which is license‑free in India. If you need 868/915 MHz operation, we offer a variant with the SX1276 module. Contact our support team before ordering, and we’ll swap the module at no extra cost.
How do I mount the solar panel outdoors and protect the connections?
The waterproof enclosure has pre‑drilled cable glands. Run the panel cable through the gland and seal it with silicone (not included). The panel can be pole‑mounted using standard brackets; we recommend orienting it southwards at a tilt equal
C33 deep-sleep node wakes every 15 min, reads sensors, transmits LoRa and returns to 10µA sleep. 2-year battery life.
