Looking to compare AHT10 vs AHT20 and find out which one is better for your use? The AHT10 and AHT20 are both humidity and temperature sensors that are commonly used in various applications. While both sensors serve the same purpose, there are some notable differences between the two.
The AHT10 is a digital humidity and temperature sensor that provides accurate and reliable measurements. It has a wide operating voltage range of 1.8V to 3.6V, making it compatible with a wide range of microcontrollers.
The AHT10 offers a humidity measurement range of 0-100% RH with an accuracy of ±2% RH, and a temperature measurement range of -40°C to +80°C with an accuracy of ±0.3°C. The AHT10 also has a fast response time of less than 8 seconds.
On the other hand, the AHT20 is an upgraded version of the AHT10 and offers some improvements over its predecessor. The AHT20 also has a wide operating voltage range of 1.8V to 3.6V, making it compatible with various microcontrollers.
It offers a humidity measurement range of 0-100% RH with an accuracy of ±2% RH, and a temperature measurement range of -40°C to +85°C with an accuracy of ±0.3°C. The AHT20 has a slightly faster response time compared to the AHT10, with a maximum of 5 seconds.
So, which one is better, the AHT10 or the AHT20?
The AHT20 is better than the AHT10. The main differences are range, availability, and temperature reading capacity. It ultimately depends on the specific requirements of your application. Here are some key points to consider:
- Accuracy: Both sensors offer the same level of accuracy, with a ±2% RH accuracy for humidity measurements and a ±0.3°C accuracy for temperature measurements.
- Temperature Range: The AHT20 has a slightly wider temperature measurement range of -40°C to +85°C compared to the -40°C to +80°C range of the AHT10.
- Response Time: The AHT20 offers a faster response time compared to the AHT10, with a maximum of 5 seconds.
- Operating Voltage Range: Both sensors have the same wide operating voltage range of 1.8V to 3.6V, making them compatible with a variety of microcontrollers.
