HS4011

HS4011 is a digital relative humidity and temperature sensor. It is a highly accurate, ultra-low power, fully calibrated relative humidity and temperature sensor with a hydrophobic membrane. The MEMS sensor features a proprietary sensor-level protection ensuring high reliability and long-term stability. The HS4011 is fully calibrated and temperature-compensated with an I²C digital output. The high accuracy, fast measurement response time, and long-term stability combined with the small package size makes the HS40xx series ideal for a wide number of applications ranging from portable devices to products designed for harsh environments. Applications include climate control systems, instrumentation, home appliances, weather stations, building automation, HVAC systems, medical equipment, data logging systems.
