Aosong Electronic Temperature and Humidity Sensor Design Guide-Use temperature and humidity sensors correctly
■ Aosong electronic temperature and humidity sensor (hereinafter referred to as the sensor) is a temperature and humidity composite sensor with calibrated digital/analog signal output, and applies dedicated digital module acquisition technology and temperature and humidity sensor technology to ensure that the product has extremely high reliability and excellent long-term stability. In order to make full use of its excellent performance and features, this document makes provisions for the design of some housings, PCBs, software, etc. and provides assistance in the design stage.
■ Please note that unreasonable design of housing, PCB, etc. may cause significant temperature and humidity deviation and increase in response time, So please design strictly in accordance with the requirements of this document.
● The most important design advice on accuracy
■ The accuracy of measurement depends not only on the accuracy of the sensor itself, but also on the design of the sensing system. The sensor collects the temperature and humidity from its direct environment, so the relativity between the local condition of the sensor and the measured condition is very important. Figures 1 to 4 ilustrate the most important design recommendations to ensure good sensor performance: contact environment, air-tightness to the air inside the housing, small dead space volume, and isolation from heat sources. The following pages contain a more in-depth introduction.
