7.3 Temperature sensor
The MCP9700A (3), an integrated low-power linear active thermistor allows
measurement of the ambient temperature. This sensor provides an analog
voltage which changes linearly with the applied temperature. This voltage
can be sampled by the A/D converter on the host MCU, making it available
for various user applications. The MCP9700A can measure the temperature
within the range from -40°C to +125°C, but the actual measurement range
is limited by the thermal endurance of the mikromedia 3 board itself.
Nevertheless, having a thermal sensor on board is very useful, allowing the
development of thermal monitoring applications, weather stations, and
similar.
