Submerge probe into fish tank to measure water temperature (Submerge probe only, do not submerge thermometer in water)

Humidity and Temperature Sensor with Direct Output

LM35 Temperature Sensor

LM35 series Temperature Sensor is a precisely integrated circuit whose voltage output is linearly proportional to the centigrade temperature. These sensors have an added advantage over kelvin calibrated sensors and do not require the subtracting of constant voltage from its output to obtain convenient centigrade scaling. Our product need not to be calibrated or trimmed to normal accuracy of ±1/4 °C at room temperature and ±3/4°C over a full -55 to 150°C temperature range.The low output impedance, linear output, and precise inherent calibration of these temperature sensors makes the interfacing to readout or control circuitry easily.These sensors can be used with single, plus or minus power supplies because it draws only 60 mA from its supply and has very low self-heating, less than 0.1°C in still air.

DHT22 Digital Temperature And Humidity Sensor Module

DHT22 capacitive humidity sensing digital temperature and humidity module is one that contains the compound has been calibrated digital signal output of the temperature and humidity sensors. Application of a dedicated digital modules collection technology and the temperature and humidity sensing technology, to ensure that the product has high reliability and excellent long-term stability.

DHT22 Digital Temperature And Humidity Sensor

The DHT22 is a basic, 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).

DHT11 Temperature And Humidity Sensor Module

This is a very popular, ultra low cost digital temperature and humidity sensor. It uses a capacitive humidity sensor, and a thermistor to measure the surrounding air temperature. The result is available via 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. But, for most applications this is not an issue at all.

DHT22 Wired (AM2302) Humidity and Temperature Sensor

AM2302 output calibrated digital signal. It applys exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements is connected with 8-bit single-chip computer.

DHT11 Temperature And Humidity Sensor

DHT11 is an inexpensive sensor that provides calibrated digital outputs for ambient temperature and relative humidity. It comes in a single row 4-pin package and operates from 3 to 5.5V power supply. It can measure temperature from 0-50 °C with an accuracy of ±2°C and relative humidity ranging from 20-95% with an accuracy of ±5%. It has got its own proprietary 1-wire protocol, and therefore, the communication between the sensor and a microcontroller is not possible through a direct interface with any of its peripherals. The protocol must be implemented in the firmware of the MCU through bit-banging of an I/O pin.
