Baby Room Comfort Monitor Kit with ESP32 + DHT22 v7
Build a Network-Manageable Baby Room Comfort Monitor with ESP32, DHT22 & SNMP
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For parents and caregivers who want a network-manageable infant room monitor, this kit guides you through building an ESP32-based system that exposes temperature, humidity, and power draw as SNMP MIB variables. A standard NMS like Zabbix or PRTG can then poll these values over UDP, enabling alerting and monitoring without a separate cloud service.
What You'll Build
You'll assemble and program a compact device that reads ambient conditions via the DHT22 sensor, measures current draw with the ACS712, and displays real-time data on the 0.96-inch OLED screen. The ESP32 then acts as an SNMP agent, serving these readings to any network management console that queries its MIB. The final module can be wall-mounted near the crib, powered by a single 5V supply, and managed entirely over your local network.
What You'll Learn
- Expose sensor readings as SNMP MIB objects that any NMS can poll over UDP
- Interface the DHT22 sensor to measure temperature and humidity accurately
- Monitor current consumption with the ACS712 hall-effect sensor for safety insights
- Display live readings on an OLED and package the circuit on a prototype board for permanent use

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring networking concepts in their computer science projects, B.Tech ECE/EEE students working on IoT and protocol stacks, or participants in Smart India Hackathon building connected healthcare solutions. If you've ever wanted to understand SNMP beyond theory and create a real agent that manages a critical environment, this kit delivers hands-on clarity.
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?
Your kit includes a QR code linking to an AI build companion trained on this exact project; you can also reach our team on WhatsApp for quick help.
Can I extend this to monitor other sensors like a PIR motion detector?
Absolutely. Once you understand how MIB variables map to sensor readings, adding a PIR sensor or an additional DHT22 is straightforward. The SNMP agent structure can be expanded with new OIDs.
Do I need an NMS software to see the data?
Any standard SNMP manager like Zabbix, PRTG, or even the command-line snmpwalk tool can query the ESP32 agent. We provide sample configuration for snmpwalk so you can test immediately.
Is this safe for a baby’s room?
The circuit runs on a low-voltage 5V supply and uses a properly insulated PSU. The kit is designed for educational prototyping, so always place the assembled device out of reach of infants and ensure cable management for safety.
Infant Care — ESP32 implements SNMP agent exposing MIB variables for sensor readings. NMS queries over UDP.
