      Description

      Grove - Temperature Sensor uses a thermistor to measure ambient temperature. The resistance of thermistor changes based on ambient temperature. This resistance value alters the output of a voltage divider which is measured by an analog input pin and converted to a temperature value. The operating range is -40 to 125°C , with an accuracy of 1.5°C .


      For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

      I'm looking for the temperature equation for the v1.1 of this. I get that the B value has changed from the sample but the equation on the SeeedStudio github produces clearly absurd results (raw value comes in at around 520-530 for room temperature).<

      <p>Has anyone found the equation for v1.1 as I've tried a few now and nothing comes close! V1.0 worked well so why the change without a suitable working solution?</p>

      <p>Sorry for the delayed reply.We have updated the wiki for V1.1/V1.2 and the new equation provides correct value.</p><p><a href="http://www.seeedstudio.com/wiki/Grove_-_Temperature_Sensor_V1.2" rel="nofollow">http://www.seeedstudio.com/wik...</a></p>

      Can you please confirm which thermistors are used on board revisions v1.0, v1.1 and v1.2?
      I am trying to find accurate B values.

      <p>v1.0 uses thermistor TTC3A103*39H with B value 3975<br>v1.1 uses thermistor NCP18WF104F03RC with B value 4250<br>v1.2 uses thermistor ??? with B value ???</p>
