1 wire grass temperature sensor

This 1 wire grass temperature sensor consists of a glass tube with a copper coil wire mounted on the end of a DS18S20. at each end of the glass tube is a plastic fitting this is sealed in place using some silicone adhesive this Has made the glass tube waterproof,

The idea behind this is to get a accurate constant temperature across the glass tube

This grass sensor was used for experimental purposes only, in our current weather station network we are using a DS18S20 in a plastic casing
