March 25, 2026 – PIR Sensor Prices Hit New Low
According to component market intelligence firm IoT Analytics, the average selling price (ASP) of basic PIR sensor modules (HC-SR501 and equivalents) has fallen below $0.50 for the first time, reaching $0.48 in March 2026. This represents a 40% decline from $0.80 in 2023.
Price Trends:
- 2023: $0.80
- 2024: $0.65
- 2025: $0.52
- 2026 (March): $0.48
The price decline is driven by massive production scale from Chinese manufacturers, process automation, and intense competition. Annual production of PIR sensor modules is now estimated at over 2 billion units, driven by demand from IoT, smart home, and security applications.
However, the price drop has raised concerns about quality. Some ultra-low-cost modules use inferior pyroelectric elements with reduced sensitivity, poor soldering and assembly quality, and inadequate electrostatic discharge (ESD) protection.
Buyers are advised to purchase from reputable distributors rather than unknown sellers on marketplaces.
IoT Analytics predicts that prices will stabilize around $0.45-0.50 for basic modules, as margins become too thin for further significant reductions. However, modules with additional features (adjustable timing, better sensitivity, lower power) may maintain higher pricing.
