Battery Powered Nano Mesh Node Kit with Arduino Nano + NRF24
Deploy a Self-Sustaining Outdoor Sensor Mesh with Arduino Nano + NRF24L01
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a network of weatherproof sensor nodes scattered across a farm, a campus, or a forest patch — each one reporting temperature and humidity back to a central logger, and running unattended for half a year on a tiny battery. This kit delivers exactly that capability. You hand-solder every connection, tune the deep-sleep schedule, seal the IP65 enclosure, and walk away with a real-world field deployment skill that engineering internships and hackathons demand.
What You'll Build
You assemble a compact LiPo-powered Arduino Nano node fitted with a long-range NRF24L01 PA LNA radio, DHT22 sensor, DS3231 real-time clock, and microSD logging. The node wakes from deep sleep on a precise RTC alarm, samples air temperature and humidity, timestamps the data, transmits it to a central receiver over a star network of up to 8 nodes, and logs a local copy to microSD — all while drawing so little current that the included 1000mAh LiPo or two AA batteries sustain it for 6 months outdoors.
What You'll Learn
- Implement Arduino deep-sleep modes and power-gating to extend battery life beyond 6 months
- Configure NRF24L01 radios for a star network topology with reliable multi-node communication
- Interface DHT22 and DS3231 to collect timestamped environmental data and store it on microSD
- Charge and protect a LiPo cell using the TP4056 module while powering the node from the same battery

Who This Kit Is For
B.Tech ECE/EEE students working on Smart India Hackathon prototypes or final-year IoT projects will find the low-power design directly applicable. ATL Tinkering Lab mentors and research scholars needing long-duration environmental logging can deploy these nodes across a campus and collect data for months without maintenance. Anyone who has built basic Arduino projects and is ready to tackle real-world constraints — power budgets, radio interference, weatherproofing — will turn theory into a deployable device.
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 open the AI companion that has been trained on every step of assembling this exact node, from soldering the PCB to debugging the radio. You can also reach us on WhatsApp and we'll help you within a few hours.
How long does the node run on batteries?
Using the supplied 1000mAh LiPo and our optimized sleep-wake cycle, a node sampling and transmitting every 15 minutes lasts over 6 months. If you prefer AA cells, an external holder (not included) lets two AAs power the node for a similar duration.
Can I expand the network beyond 8 nodes?
The NRF24L01 star network in this kit is designed for up to 8 sensor nodes sending data to one central receiver. Beyond that, you can run multiple star networks on different channels or implement a mesh, but the kit’s firmware and instructions focus on a robust 8-node star that covers most campus or farm deployments.
Is this kit suitable for outdoor deployment in Indian monsoons?
Yes. The IP65 waterproof box protects the electronics from dust and powerful water jets. Once you seal the cable gland openings with silicone or rubber grommets, the node withstands heavy rain, making it reliable for agricultural monitoring or environmental studies during monsoon season.
LiPo-powered Nano with NRF24L01 runs for 6 months on two AA batteries using deep sleep. Star network of 8.
