Hello guys
I'm Using Arduino Protenta Machine Control with 24 v power supply and 24 v digital input.
I wanna know wich sensors can I use for the tempreture outside (it has to be waterproof) ?
thanks

But, depending on the length from the Arduino base, you may need to expand your search into 'wireless' but that must include consideration on power: batteries, solar, AC availability, and so forth.

thanks for the replay
but I can't use the wierles sensor
all what I need is a waterproof sensor or any good way to make the Arduino Sensors like SHT31 waterproof.
One must be cautious with homemade waterproofing using consumer products like silicone caulk or 2-part epoxy:
- silicone is great but provides an unwanted thermal "insulation" coating which delays/impede the time for the active sensor to change temperature. Delays may be undesirable.
- 2-part epoxy 'can' generate a high heat during the curing process and may damage the sensitive component; although, I have not incurred any long term damage. Just remember that some epoxy products may cure in 5-minutes, but may generate chemical heating beyond 24 hours!
- liquid "rubber" may react and degrade with sunlight (ultraviolet) but may degrade too if ozone is in the atmosphere: (electric welding, AC power rooms, closed areas with radon, etc.)
The bead thermistors are usually ceramic devices and often conformal coated anyway: with these devices, the wire leads just need to be waterproofed as the "bead" is waterproofed.

I once had a salvaged thermistor that was in a sealed glass tube. Wires were sealed at one end of the tube. The OP can do the same. Response to changing temperature was slowed, of course.

No need if you use one of these:
