SOUSHINE NH001 Seat Occupancy Pressure Sensor – Thin Film Contact Switch for Seat Detection Systems
The SOUSHINE NH001 is a thin-film pressure sensor designed for seat occupancy detection in automotive and smart furniture systems. It provides a digital contact switch output upon pressure detection, compatible with 5V logic systems like automotive ECUs and microcontroller-based safety circuits.
Features
- Designed for seat belt reminder systems, triggering a warning light or chime for unbuckled passengers.
- Detects pressure from 150 grams up to 500 kg, suitable for both front and rear seat occupancy sensing.
- Features a fast 7 ms response time for immediate system activation upon seat contact.
- Constructed with a durable sponge and steel base housed in a plastic casing for long-term reliability.
- Includes a 40 cm cable for simplified installation and integration into vehicle wiring harnesses.

The SOUSHINE NH001 operates as a threshold-based contact switch, activating when pressure within its 150 g to 500 kg range is applied to the seat surface. This change in state is used to signal a vehicle’s electronic control unit (ECU) or other monitoring systems, primarily for occupant safety features.
Engineered for automotive environments, the sensor maintains stable operation across a temperature range of -20°C to 80°C. Its robust construction, combining a flexible sponge interface with a rigid steel base, ensures consistent performance and durability under repeated loading cycles typical in seating applications.
