Sensy32 Board is an ESP32-S3 sensor platform with up to six sensors for environmental monitoring in IoT applications

The Sensy32 Board is a compact sensor platform powered by Espressif’s flagship ESP32-S3 WiFi and Bluetooth microcontroller. The development board brings different monitoring devices together on the same PCB for easier integration into IoT ecosystems.

It is a multipurpose device with several sensors bundled to measure and monitor ultraviolet light intensity, altitude, pressure, orientation, humidity, temperature, motion, and human presence. It includes a 9-degree-of-freedom inertial measurement unit (IMU) for 3D space orientation, while the built-in MEMS microphone can be used for audio input in voice detection and noise measurement applications.

The onboard ESP32-S3 microcontroller powers the array of features and also offers Wi-Fi and Bluetooth Low Energy connectivity. The Sensy32 ESP32-S3 sensor platform also integrates an LCD screen for immediate feedback and real-time monitoring.

We have covered other ESP32-based environment sensors such as the Qsen-07 multi-sensor board, AirGradient ONE, MoreSense MS-06, and Studio LUFF’s Air Quality Sensor.

The Sensy32 ESP32-S3 sensor platform includes an “advanced and user-friendly” cloud backend that supports customized dashboards for visualizing sensor data with graphs, charts, and widgets. A single account can manage up to 10 boards, with data available for viewing in real-time and storage for up to 30 days. Upgrades will be available for users with long-term storage needs.

Unfortunately, it is not open-source, but code samples are included in the sensor board Arduino library on GitHub. The Sensy32 board is priced at around $70 on Tindie. The board appears useful but doesn’t seem very cost-effective, given its feature set and the available alternatives. More information about the product can be found on the Sensy32 webpage.
