ESP32 Deep Sleep Battery Saver Kit with ESP32 + DHT22 — a beginner-level kit for kids.

ESP32 Deep Sleep Battery Saver Kit – Build a 3-Month Battery IoT Weather Station with ThingSpeak

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 1-5 days.

Imagine a weather station that runs for three months on a single small battery, automatically waking every 15 minutes to measure temperature and humidity, then uploading the data to the cloud before going back to sleep. This kit makes that vision a reality for school projects, smart agriculture, and home environment monitoring.

What You'll Build

You'll assemble a self-contained wireless sensor node that reads the DHT22 sensor every 15 minutes, sends the data to ThingSpeak's free IoT platform, and then enters deep sleep to conserve battery. The included code and wiring diagrams make it plug-and-play – no prior coding experience needed.

What You'll Learn

• Programming the ESP32 to alternate between active mode and deep sleep for ultra-low power consumption
• Interfacing digital temperature-humidity sensors (DHT22) with microcontrollers
• Uploading sensor data to cloud platforms like ThingSpeak for remote monitoring
• Battery management using TP4056 charging module and 3.7V LiPo cells
