The KY-013 Ana­log Tem­per­a­ture Sen­sor mod­ule can mea­sure ambi­ent tem­per­a­ture based on the resis­tance of the ther­mis­tor on the board.

Com­pat­i­ble with pop­u­lar elec­tron­ics plat­forms like Arduino and ESP32.

KY-013 SPECIFICATIONS

This mod­ule con­sist of a NTC ther­mis­tor, a 10 kΩ resis­tor, and 3 male head­er pins. The ther­mis­tor resis­tance varies accord­ing to its sur­round­ing tem­per­a­ture. The val­ue of resis­tance can be used to cal­cu­late the actu­al tem­per­a­ture.

Oper­at­ing Volt­age5V
Tem­per­a­ture mea­sure­ment range-55°C to 125°C [-67°F to 257°F]
Mea­sure­ment Accu­ra­cy±0.5°C

CONNECTION DIAGRAM

Con­nect mod­ule pow­er line (mid­dle) and ground (-) to 5V and GND on the Arduino respec­tive­ly. Con­nect the mod­ule sig­nal pin (S) to pin A0 on the Arduino.

Some KY-013 have a dif­fer­ent pin arrange­ment. Please check your board before con­nect­ing.

KY-013 ARDUINO CODE

The fol­low­ing Arduino Sketch will derive the tem­per­a­ture from the ther­mis­tor using the Stein­hart-Hart equa­tion. The code will return tem­per­a­ture in Cel­cius, uncom­ment line 17 to get tem­per­a­ture in faren­heit
