The warning comes as multiple automakers begin placing orders for 2028 model year production, which requires sensor deliveries starting in mid-2027.<\/p>\n<p>According to industry estimates, total PIR sensor demand could exceed production capacity by 15-20% in 2027-2028, leading to allocation, extended lead times, and potential price increases.<\/p>\n<h2>Demand Drivers<\/h2>\n<h3>Automotive Child Presence Detection<\/h3>\n<p>The primary driver of the expected shortage is automotive demand for child presence detection systems:<\/p>\n<ul>\n<li><strong>US Hot Cars Act:<\/strong> Requires child presence detection in all new passenger vehicles by 2028 model year<\/li>\n<li><strong>EU regulation:<\/strong> Expected to mandate similar systems by 2029<\/li>\n<li><strong>China regulation:<\/strong> Under development, expected by 2030<\/li>\n<li><strong>Estimated automotive PIR demand by 2027:<\/strong> 100-120 million units<\/li>\n<li><strong>Estimated automotive PIR demand by 2028:<\/strong> 150-200 million units<\/li>\n<\/ul>\n<p>Automotive orders are long-cycle, with manufacturers placing orders 12-18 months in advance. Several major automakers have already placed orders for 2027 deliveries, consuming a significant portion of available capacity.<\/p>\n<h3>Building Automation<\/h3>\n<p>Building energy codes in the EU, California, and Japan are creating sustained demand for commercial occupancy sensors. This demand is expected to grow 10-15% annually through 2030.<\/p>\n<h3>Smart Home<\/h3>\n<p>Smart home adoption continues to grow, with PIR sensors becoming standard in lighting, security, and HVAC systems. This segment represents steady demand growth of 6-8% annually.<\/p>\n<h2>Capacity Constraints<\/h2>\n<p>Current global PIR sensor production capacity is estimated at 1.4-1.5 billion units per year. Major manufacturers have announced capacity expansions:<\/p>\n<table border=\"1\">\n<thead>\n<tr>\n<th>Manufacturer<\/th>\n<th>Current Capacity<\/th>\n<th>Expansion<\/th>\n<th>New Capacity (2028)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Panasonic<\/td>\n<td>350M<\/td>\n<td>+50M<\/td>\n<td>400M<\/td>\n<\/tr>\n<tr>\n<td>Murata<\/td>\n<td>280M<\/td>\n<td>+280M<\/td>\n<td>560M<\/td>\n<\/tr>\n<tr>\n<td>Excelitas<\/td>\n<td>150M<\/td>\n<td>+30M<\/td>\n<td>180M<\/td>\n<\/tr>\n<tr>\n<td>Chinese manufacturers<\/td>\n<td>500M<\/td>\n<td>+100M<\/td>\n<td>600M<\/td>\n<\/tr>\n<tr>\n<td>Others<\/td>\n<td>120M<\/td>\n<td>+20M<\/td>\n<td>140M<\/td>\n<\/tr>\n<tr>\n<td><strong>Total<\/strong><\/td>\n<td><strong>1.4B<\/strong><\/td>\n<td><strong>+480M<\/strong><\/td>\n<td><strong>1.88B<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>However, capacity additions are not fully online until late 2027 or 2028. The gap between demand and capacity is expected to be most acute in 2027-2028.<\/p>\n<h2>Lead Times and Pricing<\/h2>\n<p>Lead times for PIR sensors are already extending:<\/p>\n<ul>\n<li><strong>Standard HC-SR501 modules:<\/strong> 8-10 weeks (up from 4-6 weeks in 2025)<\/li>\n<li><strong>Panasonic EKMB series:<\/strong> 16-20 weeks (up from 12 weeks)<\/li>\n<li><strong>Automotive-grade sensors:<\/strong> 24+ weeks for qualified parts<\/li>\n<\/ul>\n<p>Analysts expect price increases of 10-20% for commodity sensors and 5-10% for premium sensors in 2027-2028.<\/p>\n<h2>Impact by Market Segment<\/h2>\n<h3>Automotive OEMs<\/h3>\n<p>Automakers are securing long-term supply agreements with qualified suppliers. Some are considering vertical integration (producing their own sensors) to ensure supply.<\/p>\n<h3>Commercial Building Automation<\/h3>\n<p>Specifiers may need to consider alternative sensors or accept longer lead times. Dual-technology sensors may become more attractive if they can be sourced from multiple suppliers.<\/p>\n<h3>Smart Home Manufacturers<\/h3>\n<p>Consumer electronics companies may face allocation as suppliers prioritize higher-margin automotive contracts. Manufacturers with diversified supply chains will be better positioned.<\/p>\n<h3>DIY and Hobbyist Market<\/h3>\n<p>Retail availability of HC-SR501 modules may be affected, with potential price increases and intermittent shortages. Hobbyists may need to plan projects further in advance.<\/p>\n<h2>Recommendations for Buyers<\/h2>\n<ul>\n<li><strong>Forecast accurately:<\/strong> Place orders with longer lead times<\/li>\n<li><strong>Qualify multiple suppliers:<\/strong> Don&#8217;t rely on a single source<\/li>\n<li><strong>Consider long-term agreements:<\/strong> Lock in pricing and allocation<\/li>\n<li><strong>Evaluate alternative technologies:<\/strong> mmWave radar where appropriate<\/li>\n<li><strong>Design for flexibility:<\/strong> Use sensors that can be sourced from multiple manufacturers<\/li>\n<li><strong>Build safety stock:<\/strong> Increase inventory buffers for critical applications<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>The PIR sensor industry faces unprecedented demand growth over the next three years. While manufacturers are expanding capacity, shortages and price increases are likely in the 2027-2028 timeframe. Buyers should plan accordingly and secure supply early.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>March 28, 2026 \u2013 Supply Chain Alert: PIR Sensors Face Capacity Crunch Supply chain analysts are warning of potential PIR sensor shortages beginning in 2027 as automotive child presence detection demand surges ahead of manufacturing capacity expansion.
