What touch circuit or sensor to use inside a concrete lamp?

Hi I was planning to build an Arduino based capacitive touch circuit to control a concrete lamp.

Will the touch work through 8mm thick concrete slab Any capacitive tuch sensor...

Yes, provided the concrete is non-conductive, dry, and does not contain metal reinforcement. You may need to use a very high value resistor and a large sensing plate, see:

The appearance of temperature cracks is inevitable when building concrete buildings. But it is important to control it within the limits allowed by the specification. For effective control, scientific predictions must be made to ensure the accuracy of the control. When pouring concrete, temperature sensors and thermometers such as thermistors are used to measure the temperature from the pouring, including the mold temperature, ambient temperature, etc., and timely squeezing and heat preservation and moisturizing´╝îPlease see: https://www.newbecca.com/product/36495113967 With the popularity of temperature sensors, in the construction industry, temperature sensors can be used to monitor the temperature in real time with alarms or monitoring software, so that the concrete can be properly hardened at the right temperature during the construction process. Avoid the occurrence of abnormal shrinkage, cracks and other damages caused by exposure, wind blowing, cold and other conditions during the hardening process of concrete.
