100K ohm NTC 3950 Thermistor The 3950 NTC Thermistor is a thermally sensitive resistor and the special feature of these 100K ohm thermistors is that they exhibit a large change in resistance with only a small change in temperature. The thermistor is ideally used as a temperature sensor for 3D Printer Reprap. NTC is also known as the Negative Temperature Coefficient. These thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. This Thermistor 100k NTC with 1 Meter Cable Temperature Sensor for 3D Printer Reprap. The thermistor is a thermally sensitive resistor known for exhibiting a large change in resistance with only a small change in temperature. It is important to note that a thermistor's change in resistance is non-linear. It follows a pre-defined curve which is provided by the thermistor manufacturer. Positive thermal coefficient (PTC) will increase in resistance with an increase in temperature, and negative ones (NTC) will decrease. But the formula in practice is not linear, so sometimes an accurate table of measurements is better than the linear formula.  Package Includes: 1 x 100K Ohm NTC 3950 Thermistor   Specifications: Temperature range −40°C to 270°C Dissipation power factor ≥5 mW/℃ Cable Material NTC Thin Film Thermistor Max power rating 45 mW Hot Time constant ≤7 s

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 Temperature measurement in medical equipment Temperature measurement in industrial processes Temperature measurement in automotive systems Temperature measurement in environmental monitoring Temperature measurement in consumer electronics.

AM2302 Temperature & Humidity Sensor The AM2302 temperature and humidity sensor is a digital sensor that measures both temperature and humidity. It uses a capacitive humidity sensor and a thermistor to measure the humidity and temperature, respectively. The sensor communicates with a microcontroller or other host device using a digital protocol such as the Single Wire Protocol (SWP) or the Inter-Integrated Circuit (I2C) protocol. The sensor can operate over a wide range of temperatures and humidities, and it has high accuracy and a fast response time. It is commonly used in applications such as weather stations, HVAC systems, and industrial process control. The sensor includes a capacitive humidity sensing element and an NTC temperature measuring element, connected with a high-performance 8-bit single-chip microcomputer, so it has the advantages of ultra-fast response and strong anti-interference ability. Low cost, 3 to 5v power and i/o, 2.5ma max current use during conversion. 1-1.5ma measuring current, 40-50 ua standby current. It has only 3 wires, including power and ground, meaning only one digital pin is required to interface it to a microcontroller.  Applications: HVAC Dehumidifier Weather station Humidity regulator Medical treatment Home appliances Package Includes: 1 x AM2302 Temperature & Humidity Sensor Specifications: Operating voltage 3.3V to 5V DC Operating temperature range -40°C to 80°C (-40°F to 176°F) Operating humidity range 0% to 100% RH (relative humidity) Dimensions  3 x 2 x 1cms Weight 9 grams

ASAIR Temperature and Humidity Sensor AM2302 (Original) The AM2302 is a wired version of the DTH22, in a large plastic body. It 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). 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 when using our library, sensor readings can be up to 2 seconds old.Connect the red 3-5V power, the yellow wire to your data input pin, and the black wire to the ground. Although it uses a single wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin.Compared to DTH11, this sensor is more precise, more accurate, and works in a bigger range of temperature/humidity, but it's larger and more expensive. There is a 5.1K resistor inside the sensor connecting Vcc and DATA so you do not need additional pullup resistors. Also check the AM2302 Temperature & Humidity Sensor available on Iotcart. The sensor is suitable for 0-100 percent humidity readings with 2-5 percent accuracy and -40 to 80 degrees Celsius temperature readings with ± 0.5-degree Celsius accuracy. It has a sampling rate of no more than 0.5 Hz (once every 2 seconds) and comes in a 4-pin single-row pin package for easy connection.
