ESP32 SNMP Agent Kit - DHT22 Temperature & Current Monitor
Build a Network-Manageable Sensor Monitor with ESP32 SNMP Agent 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.
Imagine querying real-time sensor data from anywhere on your network using a standard NMS console. This kit transforms a humble ESP32 into a full SNMP agent, exposing temperature, humidity, and current readings via MIB variables. Instead of just reading sensors locally, you build a device that speaks the language of enterprise network monitoring-perfect for CBSE project showcases or a standout B.Tech assignment that demonstrates both electronics and networking.
What You'll Build
You will assemble and program a compact sensor unit powered by an ESP32, which hosts an SNMP agent daemon. An NMS running on your laptop (or even a Raspberry Pi) sends UDP queries, and the ESP32 responds with structured OID-based data for DHT22 temperature/humidity and ACS712 current measurements. The OLED displays local readings, but the true power is remote visibility-vital for monitoring server rooms, lab equipment, or smart agriculture setups.
What You'll Learn
- Implement an SNMP agent from scratch on ESP32 using the SNMP library, handling GET/SET requests
- Read I2C sensor data from DHT22 (temperature/humidity) and analog current from ACS712, then map them into MIB OIDs
- Integrate an OLED display to show real-time sensor values alongside SNMP activity
- Configure an NMS (like SNMP Manager) to poll the agent over UDP and log data, learning the MIB structure

Who This Kit Is For
Designed for CBSE Class 11-12 students tackling an advanced Integrated Science or Computer Science project that merges hardware with networking. B.Tech CSE/ECE/EEE undergraduates will find it ideal for Smart India Hackathon themes or communication lab coursework. ATL Tinkering Labs and IIT/NIT project fairs also appreciate the hands-on exposure to SNMP, a real-world protocol seldom available in off-the-shelf kits.
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?
Scan the box QR to launch the AI companion trained on this exact SNMP agent project. It offers step-by-step debugging, and you can escalate to our WhatsApp support team for real-time guidance.
Can I use this with existing NMS tools like Zabbix or PRTG?
Yes. The agent implements standard SNMPv2c GET requests, so any mature NMS can poll it once you load the custom MIB definitions provided in the guide.
What if I haven't soldered before? This kit includes a soldering iron.
The AI companion includes a beginner-friendly soldering tutorial specific to this PCB prototype board and through-hole components. Practice with the included solder wire on the spare resistors first, and you'll be ready in minutes.
Is this kit suitable for monitoring a server room's temperature and current draw?
Absolutely. You'll learn to place the DHT22 for ambient readings and the ACS712 in series with a DC load. Over SNMP, you can set thresholds and alerts, building a rudimentary environmental monitor that scales with your networking skills.
ESP32 implements SNMP agent exposing MIB variables for sensor readings. NMS queries over UDP.
