Server Room Temperature Monitor Kit with ESP32 + DHT22 v6
Monitor Data Centre Temperatures for 6 Months on a Single Charge with This ESP32-C3 & DHT22 Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Servers overheat and crash without warning. With this kit, you’ll build a wireless temperature sensor that can run unattended inside a server rack for up to 6 months, sending alerts the moment things get too hot. Perfect for anyone managing a home lab, a startup’s server closet, or learning professional IoT deployment techniques.
What You'll Build
A compact battery-powered temperature monitor based on the ESP32-C3, using the ULP co-processor in deep sleep to wake up, read the DHT22 sensor, transmit data via Wi-Fi, and go back to sleep — all while sipping so little power that a 500mAh LiPo lasts half a year. The finished device slips easily into any server enclosure and becomes your first line of defence against thermal damage.
What You'll Learn
- Programming the ESP32-C3’s ULP co-processor for deep sleep wake-ups
- Interfacing the DHT22 digital temperature/humidity sensor with pull-up resistors
- Designing ultra-low-power IoT circuits for battery operation
- Connecting and charging a LiPo battery safely with a TP4056 module

Who This Kit Is For
This kit is designed for Intermediate-level makers — perfect for CBSE Class 11-12 students working on IoT projects, B.Tech ECE/EEE students building low-power wireless sensor networks for competitions like Smart India Hackathon, and hobbyists who want to monitor their home server room without running cables. It also fits well into ATL Tinkering Labs that are moving from Arduino to ESP32 for real-world IoT applications.
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?
Simply scan the QR code in the box to open your AI companion — it knows every detail of this kit and can provide instant, step-by-step troubleshooting. You can also reach us on WhatsApp for human support within hours.
Can I use this kit to monitor more than one server room or rack?
Yes, you can build multiple units and have them all report to a central dashboard like Blynk or a custom MQTT broker. The kit is designed for replication; additional sensors are easy to integrate.
How do I extend battery life beyond 6 months?
The deep-sleep code is already optimized for the included 500mAh LiPo. Using a larger capacity battery (e.g., 1000mAh) and increasing the wake-up interval can push runtime well past a year without any hardware changes.
Is this kit suitable for outdoor temperature logging?
The DHT22 is not waterproof, but you can house the assembly in a ventilated enclosure protected from direct rain for basic outdoor monitoring. For harsh environments, consider adding a weatherproof sensor module.
Data Centre — ESP32-C3 reads DHT22 in deep sleep wake cycle using ULP co-processor. 6 month coin cell battery life.
