The temperature has several types, 1. temperature for detecting the room temperature e.g., LM35, DHT11 or DHT22 and 2. Temperature to detect the body of human or monitoring health for example https://www.cooking-hacks.com/body-temperature-sensor-mysignals-ehealth-medical
and the relationship with pulse and temperature sensor on IoT are the detect or realtime monitoring for health patients, so DHT11 or DHT22 suitable to combined with BME280, etc.
The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
