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 .
Grove compatible interface
Arduino library ready
Operating voltage: 3.3~5V
Thermistor Zero power resistance: 100 KΩ

Thermistor: NCP18WF104F03RC (NTC)
Nominal B-Constant： 4250 ~ 4299K
Operating temperature range: -40°C to 125°C
Accuracy: ± 1.5°C
Hello, this is not an I2C type sensor, please refer to wiki of the product for usage: http://wiki.seeed.cc/Grove-Temperature_Sensor_V1.2/
1. What's the voltage of VCC
2. What's the operate voltage of your system.
3. could you please share you code.
I'm using the Grove Shield that came with the Dev kit set to the 5V side.
There is no code. I'm using the IoT Developer Hub, Node-Red definition with the following settings:
Yielding a result of:
Please refer the Intel Edison python code of Grove Temperature Sensor from the following link:
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).<
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?
Sorry for the delayed reply.We have updated the wiki for V1.1/V1.2 and the new equation provides correct value.
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.
v1.0 uses thermistor TTC3A103*39H with B value 3975
v1.1 uses thermistor NCP18WF104F03RC with B value 4250
v1.2 uses thermistor ??? with B value ???
Check the new wiki for updated equation for V1.2/V1.1 http://www.seeedstudio.com/wik...
I have purchased this recently and trying to follow example at http://learn.adafruit.com/tmp3...
However I do not find the resolution in millivolt/de
Can you please let me know in which document equation used at wiki:http://www.seeedstudio.com/wik... is documented. In dat
I need sensor which will be able to measure temperature 80-90-100C. Does your sensor able to measure this temperature ?
Hi there, black connector is 2.54mm.Grove connect is 2.0mm.
yes,you can.But please pay attention to the working time,this is not a industrial product,so you may not use it in a very hard situation too long.
Hi Terry, I only need to know the properties and origin of this function to adapt it to my ADC settings (12 bits and 3,3V as VCC). I think that this sensor is generic sensor and it can be used with different platforms and ADC configurations. For this,
Hi.That means VCC,GND,and SIG.
The Vref value of seeeduino is 5V and Seeeduino is a 10 bit ADC. If you select other microcontroller, you can set ADC. There is a Grove - I2C ADC using to get more precise value, you can have a try.
