DHT11 Humidity and Temperature Sensor 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). It's 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 a smaller and less expensive sensor for temperature and humidity measurement. APPLICATIONS: Measure temperature and humidity Local Weather station Automatic climate control Environment monitoring Also check the DHT11 Humidity and Temperature Sensor Module pack of 25, The module operates in the voltage range of 3.3VDC to 5.5VDC and is described as a basic, ultra-low-cost digital temperature and humidity sensor.

10K Temperature Sensor (Thermistor) A 10K temperature sensor (also known as a thermistor) is a type of resistor that changes its resistance value in response to changes in temperature. The "10K" refers to its resistance value at a temperature of 25°C, which is 10,000 ohms. Thermistors are commonly used in temperature sensing and control applications because of their high sensitivity and fast response time. They are often preferred over other temperature sensors such as thermocouples and RTDs because they are smaller, cheaper, and easier to use. There are two main types of thermistors: negative temperature coefficient (NTC) and positive temperature coefficient (PTC). NTC thermistors have a resistance that decreases as the temperature increases, while PTC thermistors have a resistance that increases as the temperature increases. Thermistors are inexpensive, easily obtainable temperature sensors.  They are easy to use and adaptable.  Circuits with thermistors can have reasonable output voltages - not the millivolt outputs thermocouples have.  Because of these qualities, thermistors are widely used for simple temperature measurements.  They're not used for high temperatures, but in the temperature ranges where they work, they are widely used. Applications: Temperature control in HVAC systems Medical equipment Industrial processes Automotive systems Environmental monitoring Consumer electronics.
