The DHT-11 Digital Temperature And Humidity Sensor is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed).

Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more. Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature/humidity.

But despite its disadvantages over DHT22, it is smaller and less expensive sensor for temperature and humidity measurement.

Note: This package does not include Arduino board, you have to buy it separately.

Features :

1. Low power consumption.
2. Relative humidity and temperature measurement
3. All calibration, digital output
4. Excellent long-term stability
5. No additional components
6. Long distance signal transmission

1 x DHT-11 Digital Temperature And Humidity Sensor- Normal Quality

The AHT20 is a high-precision but low-cost temperature and humidity sensor, which is equipped with an improved MEMS semiconductor capacitive humidity sensor element. It features a standard I2C interface and a wide voltage supply of 2V – 5V. And with the simple peripheral circuit, it performs stably even in harsh environments in the measuring range of -40~＋85℃.

This sensor can be widely used for measuring the environmental temperature and humidity of home electronic equipment, the temperature and humidity of automobiles, and so on.

Features:

These Humidity Sensors can be used to detect the environmental relative humidity. Used in many end products such as air conditioners, humidifiers, dehumidifiers, hygrometers, recorders, transmitters.

Most measurement devices usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. From calculations based on physical principles, or especially by calibration with a reference standard, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation, or changes in electrical capacitance or resistance to measure humidity changes.

Features:

1. Shock resistance
2. Vibration resistance
3. Resistance to soldering heat

Specifications:

1. Supply Voltage Max: 1V
