This is the Hannah HI-98143-04 pH/EC Transmitter with the
HI-1001 pH Sensor and HI-3001 EC Sensor. They are all high quality industry standard so are designed for continous monitoring of solutions up to 100M distant from the tank. Cheaper sensors will not last long under continous use and their range is only a meter or so..

This is the Telaire 8001 CO2 sensor that is compatable with the GrowSense Monitor. |

These float sensors can tell the GrowSense of low or high resevoir levels depending on how they are fitted. If connected in parallel many resevoirs can be protected at once. |
|
The 'Groundhog' detects a flood situation (Aaaah!) and informs the GrowSense. A sturdy and usefull piece of kit. |
|
Flow Switch to detect pump action, or lack of it. If in a continuous circulation system like NFT or Aeroponics is usefull. |

|
Pressure Door mat to detect intruders etc. |
 |
Reed switches to warn of door or window openings. Once again if chained together can cover many entrances. |
|
This PIR (Passive Inra Red) sensor has a special functionality of high immunity to electrical discharge and high light levels, handling repetitve movement (like fans) which makes its perfect for the job. Can be in the grow area or outside. |
