What is the lifespan of a temperature and humidity sensor?

The lifespan of a temperature and humidity sensor is affected by its type, operating environment, and maintenance, typically ranging from 2 to 5 years. Consumer-grade sensors (such as those for home use) can have a lifespan of 3 to 5 years if used in a mild environment (normal temperature, low humidity, and no corrosion) and properly maintained. However, if exposed to high temperature, high humidity, dust, or corrosive gases for extended periods, their lifespan may be reduced to less than 2 years. This is primarily due to aging of the humidity sensor and corrosion of the circuitry, leading to decreased accuracy or failure. Industrial-grade sensors are more durable and have a higher level of protection, typically with a lifespan of 3 to 5 years. Some precision-grade sensors (such as those for laboratory use) can last for over 5 years with regular calibration and maintenance. The battery life of wireless sensors can affect the overall user experience. The battery typically lasts 6 to 24 months, and the sensor can continue to function after replacing the battery. However, if core components (such as sensors and chips) deteriorate, they still need to be replaced. The key factor affecting the lifespan is the stability of the humidity-sensitive element. After long-term use, the humidity-sensitive material will gradually fail, resulting in a decrease in humidity measurement accuracy. Therefore, regular calibration is required. If the error exceeds the allowable range, the sensor must be replaced in time to ensure accurate detection data.
