Build a Wireless Temperature Monitor with Arduino Nano and NRF24L01 – Your Introduction to 2.4GHz Communication

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 small device in your garden that sends live temperature and humidity to a screen in your room – without a single wire between them. This kit lets you build exactly that: a sensor node with an Arduino Nano and DHT22, and a display node with an OLED screen, connected by NRF24L01 radios. It’s a hands‑on start to the same 2.4GHz technology that powers WiFi, cordless keyboards, and smart home sensors.

What You'll Build

You’ll create a two‑node wireless temperature and humidity monitor. The sensor node sits in the environment (kitchen, terrace, classroom) and broadcasts readings every few seconds. The receiver node picks up the data and shows it on a bright 0.96‑inch OLED. It’s a real working system you can expand into a multi‑room weather station or an IoT dashboard.

What You'll Learn

• How to establish reliable 2.4GHz communication between two NRF24L01 modules
• Reading precise temperature and humidity values from the DHT22 digital sensor
• Displaying live sensor data on an I2C OLED screen with custom graphics
• Building a complete wireless data link – sensor, transmission, and display – from scratch

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for curious kids aged 10–15, CBSE middle and high school project submissions, and ATL Tinkering Labs teaching wireless basics. B.Tech ECE students starting with RF modules will also find it a clean, ready‑to‑run first project. Parents looking for a focused weekend STEM activity will appreciate that everything arrives in one box.

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.
