1. For the High temperature sensor, it uses to measure high temperature up to 600 degree C. If you want to use to measure the temperature inside card, you can use normal temperature sensor.
You can connect the sensor to A0 port of base shield, which includes a0 and a1 pins. If you do not have base shield, you can follow below connection.
||Grove-High Temperature Sensor
HighTemp ht(A1, A0);
Serial.println("grove - hight temperature sensor test demo");
Serial.println(ht.getThmc()); //high temp
Serial.println(ht.getRoomTmp()); //room temp
2. For the grove temp sensor, thanks for the inputs, I will update the wiki.
