What are some affordable temperature sensors for my project?
There are several budget-friendly temperature sensors you can consider, such as the DS18B20, DHT11, and LM35. Do you have a specific application in mind?
I'm looking to use it for a home automation system.
For home automation, the DHT11 is a great choice as it measures both temperature and humidity. It's easy to interface with microcontrollers like Arduino.
What about accuracy and range?
The DHT11 has an accuracy of ±2°C and a range of 0 to 50°C. If you need better accuracy, consider the DHT22, which is slightly more expensive but offers better performance.
Are there any other options that are even cheaper?
You might also look into thermistors, which can be very inexpensive. However, they may require more calibration and additional circuitry.
