Cable Probes are a family of miniature environment sensors. At the moment, Tibbo offers four Probe types: ambient temperature sensor (CP#01), ambient temperature and humidity sensor (CP#02), ambient light sensor (CP#03), and IR receiver/transmitter (BP#04). The Probes are functionally compatible with Tibbits #29, #30, #28, and #27 respectively.
Compared to their Tibbit counterparts, Cable Probes offer several advantages:
The accuracy of temperature (#29) and temperature/humidity (#30) Tibbits suffers from the internal heat generated by the Tibbo Project System (TPS). External Cable Probes #01 and #02 solve this by being outside of the TPS enclosure.
The ambient light sensing Tibbit #28 and IR receiver/transmitter Tibbit #27 are at a disadvantage because, being a part of the TPS system, they cannot be easily pointed in the required direction. In contrast, Cable Probes #03 and #04 can be easily mounted in the desired place and orientation.
Cable Probes are inconspicuous and can be mounted on walls and ceilings without attracting unwanted attention. The Probes come with a 100cm cable and are available with and without mounting ears.
