Sensor Modules

Introduction

Welcome to the world of SenzConnect a smart, secure, and scalable sensor-based monitoring platform. Whether you’re tracking sensor data like temperature, humidity, CO₂ levels, or integrating with cloud systems via MQTT or REST APIs, this guide helps you set up your device in just a few steps.

Supporting Features:

• Wi-Fi Access Point Mode: The device can broadcast its own Wi-Fi hotspot with a unique SSID and password.
• Wi-Fi Station Mode: It connects to existing Wi-Fi networks with support for DHCP and static IP.
• HTTPS Communication: Secure access to the web dashboard using SSL/TLS.
• MQTT/MQTTS Integration: The device can publish sensor data to MQTT brokers with support for secure MQTTS communication.
• REST API Support: Developers can access sensor data and device functions via standard HTTP REST APIs for seamless integration.
• Sensor Calibration: Built-in calibration options help maintain accurate sensor readings.
• Factory Reset and Reboot: Device can be rebooted or reset to factory settings via dashboard.
• Data Logging: Stores sensor data locally.

Prerequisites

Before you begin, make sure you have:

1. A SenzConnect module.
2. A power source (USB or adapter).
3. USB C cable.
4. A Wi-Fi-enabled device (laptop or smartphone).
5. Access to your Wi-Fi network.
6. A modern web browser (Chrome, Safari, Edge, etc.).
7. Optional: MQTT broker details, SSL certificates (for HTTPS and MQTTS).

Let’s get started

Follow these steps to set up and start using your SenzConnect module:

Step 1: Power the Device

The SenzConnect Module operates using a single standard 5V USB-C cable. Use any 5V, 1A USB-C adapter or power source to power the board reliably. Once powered, the Power LED glows solid red for 2 seconds, signaling that the system has started properly.

Step 2: Configuration Mode: The Access Point Mode

The SenzConnect  Module features a built-in Wi-Fi Access Point (AP) made for easy, direct configuration, no app or special software needed.

1. Connect to the Access Point:
   • On Power on the device automatically enters AP mode, indicated by a blinking purple LED.
   • On your PC or mobile device, open Wi-Fi settings.
   • Look for a network with the SSID similar to the module’s Default Hostname.
   • Connect to it using the Default Password.
   • Once connected, the purple LED will turn solid, confirming successful connection.
2. Accessing the Configuration Page:
   • Open any web browser and enter: 192.168.4.1.
   • Login using the default credentials when prompted.
   • You will now see the configuration dashboard.
3. Explore the Web Dashboard
   • View live sensor readings (like temperature, humidity, CO₂ and more).
   • Change network settings.
   • Configure MQTT/MQTTs.
   • Upload HTTPs/MQTTs certificates.
   • Perform reboot or factory reset.
   • Calibrate sensors for better accuracy.
4. Reboot

Note: Once all the necessary settings are completed, reboot the device to enable the set changes.

You can reboot the device in two ways:

• From Web Interface: Click Reboot on the Device settings page under the Device Management section.
• Using the Multi-Purpose Switch: A single click will reboot the device with the saved configuration.

Step 3: Application Mode: The Station Mode

1. From the dashboard, go to Network Settings.
2. Choose automatic IP assignment (DHCP) or configure a manual IP.
3. Enter your Wi-Fi credentials (SSID & password) to connect to your local Wi-Fi network.
4. The device on reboot will switch to Wi-Fi Station mode. The LED will blink green while connecting and turn solid green when connected to the network of your choice.

Step 4: HTTPS Settings

Enabling HTTPS ensures secure, encrypted communication with the device dashboard.

1. What You Need:
   • Server Certificate (.pem): Authenticates the device.
   • Server Key (.pem): Matches the certificate and secures the session.
2. How to Enable:
   • Upload the certificate and key via the web interface in the Network Settings Page under the HTTPS Settings section.
   • Reboot the device to apply changes.

On the next power on, you can access your SenzConnect device over HTTPs.

Step 5: MQTT/MQTTS Integration

The SenzConnect Module can publish real-time sensor data to your MQTT broker, supporting both unencrypted (MQTT) and encrypted (MQTTS) communication.

1. Make sure the device is connected to Wi-Fi network of your choice in Station Mode.
2. Go to MQTT Settings on the dashboard.
3. Enter the Broker details.
4. Enable MQTTS (if required) by uploading the client and CA certificates along with the Client key.
5. Submit and reboot the device.

Once the device is rebooted, it connects to the configured MQTT/MQTTs broker and starts publishing the data. The connectivity status and the publish status can be viewed on the LED indicator.

Step 6: Sensor Calibrations

Improve accuracy by calibrating sensors under The Sensor Settings page on the web interface.

Step 7: Backup Management

SenzConnect modules support easy backup and restore of configuration data to simplify deployment and maintenance. From the web dashboard, navigate to the Device Settings tab and click Download under the Backup Management Section to save current data as a csv file on your local device.

Step 8: Device Management

1. Reboot
   • Applies settings or refreshes device behavior.
   • Initiates reconnection to the network.
2. Factory Reset
   • Restores all settings to factory defaults.
   • Erases saved Wi-Fi, MQTT, calibration, and password information.

⚠️ Use Factory Reset only when necessary. Always back up your configurations and data before a Factory reset.

Best Practices

• Secure your credentials and HTTPS keys.
• Back up your configurations and data before factory reset.
• Ensure stable network connection for consistent data publishing.
