Wireless Temperature & Humidity Monitoring with the NRF24 Sensor Link Kit and Arduino Uno

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 monitoring the climate of a greenhouse, server cabinet, or remote room without running a single wire. This kit turns that into a working prototype: you’ll assemble a transmitter that reads temperature and humidity from a DHT22 and sends it through an NRF24L01 module to a receiver Arduino that displays live data on a clear 16x2 LCD. It’s a complete wireless sensor link designed to teach you the real-world RF communication challenges and solutions.

What You'll Build

A fully functional wireless sensor node. The transmitter circuit captures DHT22 readings, packages them, and transmits via 2.4GHz NRF24L01. The receiver circuit decodes the data and shows temperature and humidity on a backlit LCD updated in real time. You’ll power both units from 9V batteries, with all necessary decoupling capacitors included to tame the notorious NRF24 noise issues that cause dropped packets or erratic readings.

What You'll Learn

• Configure NRF24L01 modules for reliable point-to-point communication
• Interface the DHT22 sensor to read accurate temperature and humidity values
• Drive a 16x2 LCD using the I2C backpack to save Arduino pins and simplify wiring
• Tackle noise and brownout problems with strategic capacitor placement on breadboards

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate-level kit is built for CBSE Class 11-12 students tackling physics practicals or computer science investigatory projects that require wireless data logging. B.Tech ECE and EEE students will find it invaluable for understanding IoT protocols before heading into campus hackathons like Smart India Hackathon. ATL Tinkering Lab facilitators and hobbyists from IIT, NIT, VIT, and BITS will appreciate the pre-validated hardware that removes the guesswork from RF breadboarding.

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.
