The temperature sensor BT01 is a low-cost, general-purpose temperature sensor that can be used to measure temperature in the range of -40°C to 140°C, in liquids (water, mild acidic solutions) and air. The sensing element of the sensor is an NTC thermistor, which is positioned in a stainless steel tube. The thermistor is a variable resistor whose resistance decreases nonlinearly with increasing temperature.
Range: -40°C … 140°C
Accuracy: 2 ̊C at -40 ̊C; 0.6°C at 30 ̊C; 1.8 ̊C at 140 ̊C
Can be used to:
• monitor indoor and outdoor temperatures,
• monitor freezing and boiling water,
• investigate the temperature during endothermic and exothermic reactions,
• investigate evaporation.
