DHT22 Digital Temperature and Humidity Sensor-Standard Quality
DHT22 Digital Temperature and Humidity Sensor-Standard Quality
The DHT22 Digital Temperature and Humidity Sensor (Standard Quality) is an affordable, easy-to-use sensor that measures both temperature and humidity. It utilizes a capacitive humidity sensor and a thermistor to detect environmental conditions, outputting a digital signal on the data pin—no need for analog input.
While the sensor is straightforward to use, it requires careful timing to read the data. One limitation is that you can only retrieve new data every 2 seconds, meaning sensor readings may be up to 2 seconds old when using the provided library.
To use the DHT22, simply connect the leftmost pin to a 3-5V power source, the middle pin to your data input, and the rightmost pin to ground. Although it sends data via a single-wire connection, it is not compatible with Dallas One Wire protocol. If you plan to use multiple sensors, each one must have its own dedicated data pin.

LM35D Analog Temperature Sensor Module without cable
s is LM35D Analog Temperature Sensor Module without cable
This LM35D Analog Temperature Sensor Module is based on the semiconductor LM35 temperature sensor. The LM35 Linear Temperature Sensor module is useful in detecting ambient air temperature. Sensitivity is 10mV per degree Celsius. The output voltage is proportional to the temperature.
LM35 is a precision IC temperature sensor with its output proportional to the temperature (in °C). The sensor circuitry is sealed and therefore it is not subjected to oxidation and other processes. With LM35, the temperature can be measured more accurately than with a thermistor!!!
