Sensors
- Determine required sensitivity and periodicity for each sensor.
Water Temperature
- Colin
RTP - Ruggedized Wide Range Temperature Probe
- 9 or 12 bit resolution
- 12 foot CAT 5 cable
- Dallas Semiconductor DS18S20 or DS18B20 sensors
- uses 1-Wire communication protocol
The RTP temperature probe is designed for wide temperature range applications requiring excellent chemical resistant properties and sensor submersion.

- eXtended Digital I/O functionality including pulse-width modulation, quadrature and edge counting, and pulse timing with IRQ/DRQ support.
- TS-DIO64 Digital I/O Board, which is a 8-bit PC/104 (standard format) peripheral board that provides 64 digital I/O points (32 inputs plus 32 outputs). Up to 4 TS-DIO64 boards may be installed into a single system, enabling up to 256 DIO points (128 inputs plus 128 outputs). The TS-DIO64 DIO functions are compatible with any PC/104 SBC including all the Technologic Systems ARM and X86 products.
