SB040152025 – INFRARED DETECTOR SCHEMATIC BLOCK

This schematic block features the TSSP95038TR, a compact infrared (IR) receiver designed for detecting 940 nm IR light with a 38 kHz carrier frequency. The device outputs an analog “active‑low” signal when it senses modulated IR bursts, making it suited for proximity detection, presence sensing, and remote control receiver applications.

Packaged in a small 4‑SMD J‑lead case, this breakout module makes it easy to connect to a microcontroller or analog input. It operates with low supply voltage and is well suited for robust, compact proximity or IR‑based detection systems.

Key Features:

• IR receiver sensitive at ~940 nm
• Designed around a 38 kHz modulation frequency
• Analog active-low output
• Supply voltage range: 2.0 V to 3.6 V
• Operating current: ~5 mA in typical use
• Operating temperature: –25 °C to +85 °C
• Compact 4‑SMD package in J‑lead form
• Good detection range for reflective or remote IR use

Typical Applications:

• Presence or proximity sensing (e.g. people detection, object detection)
• IR remote control signal reception
• Reflective light barriers
• Embedded automation and safety systems
• Robotics and machine vision presence detection
• Low-cost IR-based triggering or wake-up circuits

By integrating this Quickboards schematic block, engineers can quickly prototype IR-based detection systems, minimize external analog components, and leverage a production-ready, compact IR receiver for presence, proximity, or remote‑control applications.
