SB040242025 – INFRARED TEMP SENSOR SCHEMATIC BLOCK

This schematic block features the ZTP‑148SRC1, a non-contact infrared (IR) temperature sensor in a TO‑46 metal can package. It measures the temperature of objects by detecting their infrared radiation, providing a voltage output proportional to the detected IR energy. The sensor also includes an internal thermistor for ambient temperature compensation, enabling accurate object temperature measurement without direct contact.

Packaged in a compact TO‑46 metal can with a flat IR filter, this breakout module exposes power, ground, and analog output pins, allowing rapid integration with microcontrollers or ADCs. Its non-contact design makes it ideal for monitoring moving or hard-to-reach objects, surfaces, or environments where traditional contact sensors are impractical.

Key Features:

• Non-contact infrared (IR) temperature sensing
• Measures object temperature via emitted IR radiation
• Built-in ambient temperature compensation thermistor
• TO‑46 metal can package for reliable thermal response
• Object temperature range: –20 °C to +100 °C
• Wide field of view (~80–90°)
• Supply voltage: 2.7–5.5 V
• Low power consumption (~1 mA)
• Compact and robust design suitable for embedded systems

Typical Applications:

• Non-contact temperature monitoring of objects and surfaces
• HVAC and environmental control systems
• Industrial process monitoring
• Portable or wearable temperature measurement devices
• Robotics and automation requiring contactless sensing
• Educational and prototyping projects

By integrating this Quickboards schematic block, engineers can implement accurate non-contact temperature measurement, reduce analog interface complexity, and take advantage of a compact, reliable IR sensor for embedded and industrial applications.
