Maintenance of plant temperature meter
When the camera – the lens in particular – is polluted, this may influence the measuring results. Therefore, you should check the camera on pollution every three months and clean it if necessary. Dust can simply be removed by means of pressurized air. Tough dirt can be removed with a tissue or cotton cloth with alcohol or methylated spirit. Never use aggressive detergents or scouring agents; this will damage the device!
In addition, always shield the lens of the camera when applying crop protection agents in the greenhouse. To do this, use the included plastic protective cover cap. If you clean the greenhouse using aggressive detergents, then shield the entire device to prevent damage.
