Vehicle-mounted temperature and humidity sensor 'SHT41A-AD1B'

Sensirion exhibited at the "Automotive Technology Exhibition 2026 Nagoya," held at Aichi Sky Expo from June 17 (Wednesday) to June 19 (Friday), 2026. At this exhibition, we introduced sensor solutions for automotive applications. We also showcased various measurement demonstrations and new products for the first time at the exhibition, allowing many visitors to see the performance and technological capabilities of our products. We sincerely thank all the attendees. ■ Exhibits Measurement Demos: SWS4A: Direct water detection sensor for ADAS SPS6x, STC42A: Battery thermal runaway detection sensors SAEN6x: Integrated combo module for HVAC SACD4: Refrigerant (propane) leak detection sensor module SAAF4: Window fog detection sensor module

The LiDAR systems, essential for autonomous driving and ADAS, are exposed to harsh environments such as rain, snow, and humidity. Seal failures can lead to moisture intrusion and excessive humidity within the LiDAR housing over time, causing fogging and corrosion of electronic components, which can result in system failures. Continuous monitoring of moisture intrusion is crucial for stable operation and safety. Solve it with the SHT41A! Sensirion's SHT41A temperature and humidity sensor is an automotive-grade product that enhances the reliability of LiDAR systems, achieving high-precision measurements even in harsh environments. ■ Features - AEC-Q100 certified - Operating range: 0–100% RH, -40–125°C - Low voltage support: 1.08V–5.5V - Ultra-low power consumption: average 19µA - High precision: ±2% RH, ±0.2°C - Size: 1.5 × 1.5 × 0.5 mm³ ■ Main Applications - LiDAR systems (ADAS/autonomous driving) - Cameras, radar, steer-by-wire/brake-by-wire - ECU, CCU - Battery management, charging systems For product specifications or any inquiries, please contact us or use the document download option.
