Gravity: Analog High Temperature Sensor (30~350°C)

Analog High-Temperature Sensor Module with PT100 Probe provides reliable measurement for environments far beyond the range of common digital temperature sensors. Many standard temperature sensor modules such as the DS18B20 operate only up to about 125°C, limiting use in industrial or thermal‑process scenarios. This PT100‑based sensing solution adopts a resistance temperature detector (RTD) probe widely used in industrial monitoring, enabling stable measurement from 30–350°C through an analog interface. Compatibility with 3.3V–5.5V logic allows straightforward integration with development platforms including Arduino, STM32, and other embedded control systems used in robotics, automation, and laboratory instrumentation.

Industrial-Grade PT100 Temperature Detection

This high‑temperature measurement module uses a PT100 resistance temperature detector probe commonly deployed in industrial instrumentation and process monitoring. RTD technology provides excellent stability, repeatability, and resistance to electrical noise compared with many low‑cost digital sensors. The sensing probe supports an extended probe working temperature from −20°C to 400°C while the signal conditioning module measures accurately within the 30–350°C operating range, enabling precise monitoring of heating systems, laboratory equipment, or manufacturing processes.

Wide Voltage Compatibility for Embedded Platforms

The analog sensing board operates from 3.3V to 5.5V, making this high‑temperature sensing solution compatible with a wide range of microcontroller platforms and embedded systems. Stable analog voltage output between 0.2V and 2.8V simplifies integration with ADC inputs on microcontrollers, industrial controllers, and data acquisition boards. Such electrical flexibility supports deployment in automation projects, robotics systems, and experimental setups requiring reliable thermal monitoring without complex communication protocols.

Gravity 3‑Pin Analog Interface for Rapid Integration

Integration becomes straightforward through the standard 3‑pin Gravity interface and included analog sensor cable. This plug‑and‑play connection format reduces wiring complexity and improves reliability in prototype or educational environments. The analog output design also allows straightforward calibration and signal processing within embedded firmware, making the module suitable for rapid prototyping, research instrumentation, and engineering development platforms requiring quick temperature sensing deployment.

Typical applications include high‑temperature monitoring in heating equipment, industrial process control experiments, laboratory thermal measurement setups, and embedded systems requiring stable RTD‑based temperature sensing. The combination of a PT100 probe, analog conditioning circuit, and wide voltage compatibility makes this sensing module a practical thermal measurement tool for robotics, automation prototypes, and STEM Education engineering projects.
