1, product overview;

AHT15  is  temperature  and  humidity  sensor , which  use  standard  pitch  plug connectors for easy replacement in applications. In terms of protective performance, AHT15 uses PTFE film with waterproof and dust-proof performance without affecting RH signal response time.Therefore, it allows the sensor to be used in severe environmental conditions to ensure the best accuracy performance, making AHT15 the best choice in the most demanding application conditions. Each sensor is rigorously calibrated and tested. Because of improved sensors and miniaturization, it is more cost-effective.
