The integration of the HTS221 relative humidity sensor in portable devices (PDs) such as smart phones and wearable devices, or in weather stations or air conditioning equipment shall be implemented without compromising sensor performance. DHT11 can be interface with any microcontroller like Arduino, Raspberry Pi, etc. Humidity Sensor: Storage and Handling Guidelines 4 Application In Extreme Environments Some applications require usage of the HDC in harsh environments. In 9 point characterisation method, humidity levels are swept the through the RH values and measuring the corresponding dc output voltage for the individual sensor: Values are taken at humidity levels of 0%, 25%, 53.2%, 75.3%, 93.8%, 75.3%, 53.2%, 25% and 0%. Step two: After step one, keep the AM2302 sensor at condition of Temperature 20~30Celsius, humidity >70%RH for 5 hours. The fabrication of this sensor consists of the etching of p -type silicon with an HF-ethanol mixture to produce a 2.8 μm layer of pores which are an average of 6.1 nm in diameter. In this example, you will learn how to use this sensor with Arduino UNO. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and sends a digital signal on the data pin. Your specialist in innovating humidity & temperature sensors Digital-output relative humidity & temperature sensor/module DHT22 (DHT22 also named as AM2302) Capacitive-type humidity and temperature module/sensor Thomas Liu (Business Manager) Email: thomasliu198518@yahoo.com.cn 1. 2. The humidity sensor and fan controller senses the humidity of your bathroom and turns your bath fan or fan/light on when the humidity gets too high, reducing condensation in your bathroom and increasing ventilation when used in other household spaces. he humidity sensor is a small capacitor consisting of a hygroscopic dielectric mate - rial placed between a pair of elec - trodes. Long term exposure to conditions outside normal range, especially at high humidity, may temporarily offset the RH signal (e.g.+3%RH after 60h at >80%RH). Operating specifications: (1) Power and Pins Power's voltage should be 3.3-6V DC. After returning into the normal temperature and humidity range the sensor will slowly come back to DHT11 is a low cost humidity and temperature sensor which provides high reliability and long term stability. Humidity Sensor - A humidity sensor senses,measures and regularly reports the relative humidity in the air. When power is supplied to sensor, don't send any instruction to the sensor How to use DHT11 Sensor: The DHT11 Sensor is factory calibrated and outputs serial data and hence it is highly easy to set it up.
