Can you tell me which sensor will best work in medical system in terms of accuracy and speed?

In reply to CombaSof. DS1621 is the best.

I would like to add a humidity sensor to a 1-wire setup as above anyone suggest a 1-wire compatible sensor

I have two waterproof ds1820 sensors running over cat 6 cable. The Arduino is inside and the cable runs into the greenhouse about 5 metres of cable then carries on to a place on the fence at the end of the garden that is always in the shade to get an accurate shade temp reading. This is approx a further 9-10 metres.
I upload my readings to Cayenne cloud based server with apps to view readings every 3 minutes.
This has been running stable readings for over 6 months now.
I did find that joints need a good solder connection and all screened. I doubled up two of the eight available wires for each line. (Ground,data,power)
I originally used 5volt pin on Arduino and I did find I got some failed to reads now and again usually during very cold nights. The readings also oscillated a few points.
After experimenting after reading some comments about RF interference etc. I found that it worked better on the 3.3 volt pin. The readings are much smoother and an odd failed to read a month which I filter out.

Hello Orwa,
This comparison guide might help: https://randomnerdtutorials.com/dht11-vs-dht22-vs-lm35-vs-ds18b20-vs-bme280-vs-bmp180/

I’ve never tried that, but I don’t think that would work with any of these sensors. You might need to have two boards exchanging sensor data.

I’ve just added the temperature ranges to each sensor in this post.
We also created a dedicated guide comparing different temperature sensors (DHT11 vs DHT22 vs LM35 vs DS18B20 vs BME280 vs BMP180): https://randomnerdtutorials.com/dht11-vs-dht22-vs-lm35-vs-ds18b20-vs-bme280-vs-bmp180/

I would love to build an outdoor temperature probe cabled to an indoor Arduino-based digital readout. Are any of these digital protocols capable of running over long distances? My temperature sensor would be about 10 meters away from the Arduino.

Every project I’ve seen is always about low temperature sensors and never about how to utilize Type K hermocouples and RTDs utilizing the MAX31865 and MAX31855 amplifier boards. An OLED display would also be a great addition to such a project together with WIFI to a home network
