The SYH-2R Humidity Sensor (no case) is a compact, analog humidity sensor designed to deliver precise measurements of ambient moisture. By changing resistance with varying humidity levels, it provides accurate, real-time data across a wide range of 10% to 95% RH. With excellent ±3% RH accuracy at 25°C and a broad operating temperature range from -20°C to +85°C, this sensor is ideal for demanding environments. Its small footprint and open design (without casing) allow easy integration into custom electronics, weather monitoring systems, HVAC solutions, and IoT applications. Lightweight, reliable, and power-efficient, the SYH-2R is a practical choice for humidity measurement in both experimental and industrial use. Featured By RoboticsBD.
