ESP-NOW Peer Communication Kit – Build a Direct Wireless Sensor Link Without a Router

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Two ESP32 boards exchange temperature and humidity data directly over ESP-NOW — no WiFi router, no internet, just a robust peer-to-peer link. One board reads sensor data from a DHT22 and transmits it wirelessly; the second board displays those readings instantly on a 0.96-inch OLED screen. This kit strips away networking complexity so you experience pure device-to-device communication, essential for smart agriculture, remote monitoring, and battery-operated sensor nodes.

What You'll Build

You will assemble a complete wireless data pipeline: a transmitter ESP32 with a DHT22 temperature and humidity sensor, and a receiver ESP32 with a 0.96-inch OLED display. Once programmed, the sensor board sends live environmental data every few seconds to the receiver — all without connecting to a router or entering any SSID passwords. Build this in an afternoon and you’ll have a working demo of one of the most reliable low-power IoT protocols available today.

What You'll Learn

• Understand the ESP-NOW protocol and how it differs from WiFi and Bluetooth
• Program ESP32 boards for peer-to-peer data transmission using Arduino IDE
• Interface a DHT22 sensor to read accurate temperature and humidity
• Drive an I2C OLED display to output live sensor data
