This project shows how to use Tibbit #22 with an RTD sensor.
RTD sensors excel in applications that require a broad measurement range. Certain RTDs supported by TPS can measure from –200°C to +1000°C, covering temperatures that integrated-circuit (IC) sensors cannot handle.
In this project, there are two variables:
temp_rtd, a "float" data type variable.- Automatically generated when Tibbit #22 is added to the board.
- Corresponds to the connected RTD sensor's temperature.
max_temp, a "value(number)" data type variable.- User-defined.
- Used for triggering a warning when temperatures exceed its value.
The logic behind this project is simple. Every five seconds, if temp_rtd is above max_temp, a warning message is printed and TPS beeps three times. If if temp_rtd is below max_temp, then max_temp is printed with no beeping.
