{"product_id":"sparkfun-qwiic-pt100-ads122c04","title":"SparkFun Qwiic PT100 - ADS122C04","description":"\u003cp\u003eDo you need to measure temperature accurately and reliably? This could be the perfect solution! The SparkX Qwiic PT100 is based on the ADS122C04 24-bit ADC and is perfect for measuring temperature with a 100 Ohm Platinum Resistance Thermometer (PRT).\u003c\/p\u003e \u003cp\u003ePRT sensors use a thin strip of platinum to measure temperature. The resistance changes with temperature according to the laws of physics and remember \u003cem\u003e�Ye cannae change the laws of physics�\u003c\/em\u003e! By passing a small (1mA) current through the PRT, the ADS122C04 is able to measure the sensor�s resistance very accurately and the Arduino library converts this to temperature using a polynomial equation. PRT sensors can be used to measure temperatures in the range -200°C to +850°C depending on which sensor you choose. The sensors are extremely stable and do not age the way other resistance sensors can.\u003c\/p\u003e \u003cp\u003eThe Qwiic PT100 can be configured so it can use 2-wire, 3-wire or 4-wire sensors. Why is this important? Well, normally the resistance of your sensor cable would degrade the accuracy of your temperature measurement. Adding an extra Ohm of cable resistance could throw your measurement off by more than 2 degrees. 3-wire or 4-wire sensing automatically compensates for the cable resistance, providing true temperature measurement with long cables. The ADS122C04 can sample at 20Hz and has a built-in digital filter so it can \u003cem\u003eautomatically\u003c\/em\u003e reject 50Hz and 60Hz power noise, making it the perfect choice for scientific and industrial applications.\u003c\/p\u003e \u003cp\u003eOur \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_ADS122C04_ADC_Arduino_Library\"\u003eArduino Library\u003c\/a\u003e includes a full set of examples from reading the temperature in Centigrade or Fahrenheit through to being able to manually configure the ADS122C04 and read the raw ADC measurement. Want to use the PT100 as a 24-bit single-ended or differential ADC? You can absolutely do that! The library functions give you all the flexibility you need.\u003c\/p\u003e \u003cp\u003eOut in the field and don�t have the datasheet to hand? Don�t worry! Flip the board over and you�ll find a connection guide for 2-wire, 3-wire and 4-wire configurations. The sensor is attached using latch terminals so you don�t need a screwdriver either!\u003c\/p\u003e \u003cp\u003eNeed to use multiple sensors? The Qwiic PT100 can be configured with four different I\u003csup\u003e2\u003c\/sup\u003eC addresses so you can connect four together on a single I\u003csup\u003e2\u003c\/sup\u003eC bus. If you need to connect more than four then the \u003ca href=\"https:\/\/www.sparkfun.com\/products\/14685\"\u003eSparkFun Qwiic Mux\u003c\/a\u003e will let you do that.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e A PT100 sensor is required for use. Any three or four wire PT100 sensor will work. Lucky for you we have a three wire sensor! Please look through the Hookup Accessories to find the PT100 sensor.\u003c\/p\u003e \u003cp\u003e\u003cem\u003eThe SparkFun Qwiic connect system is an ecosystem of I\u003csup\u003e2\u003c\/sup\u003eC sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can�t hook it up wrong.\u003c\/em\u003e\u003c\/p\u003e \u003cp\u003e\u003cem\u003eThe Qwiic PT100 can also be automatically detected, scanned, configured, and logged using the \u003ca href=\"https:\/\/www.sparkfun.com\/products\/16832\"\u003eOpenLog Artemis\u003c\/a\u003e datalogger system.
