The University of Glasgow has created a pH sensor for soil testing that can be composted at the end of its life. It is an impedance-based sensor, using screen-printed interdigitated carbon-based ...

Their dual-sensor system addresses this through continuous pH monitoring and automated correction of infection measurements using sophisticated algorithms that analyze both square wave voltammetry and ...

CO Monitoring Realtime with ESP32 and MQ-7 Sensor This project involves using an ESP32 microcontroller and MQ-7 CO sensor to monitor CO (Carbon Monoxide) levels in real-time. The data is continuously ...

The schematic in Figure 2 outlines a design aimed at simplifying sensor testing with the ESP32-S3 module as the central controller. The ESP32-S3 was chosen for its dual-core capabilities and strong ...

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.

While some details haven’t been finalized yet, the basic elements include an ESP32-S3 system-on-a-chip combined with a small E Ink display and a custom printed circuit board with a QWERTY keyboard.

M5Stack M5PoECAM-W V1.1 is a PoE camera module built around the Espressif ESP32 MCU and WIZnet W5500 Hardwired TCP/IP embedded Ethernet controller. The W5500 along with a PoE controller takes care of ...

In recent years, research in the field of sensors has been rapidly advancing. As a result, this study proposes a pH sensor based on a magnesium oxide (MgO) thin film. The MgO sensing layer of the pH ...
