First, product overview;

AHS01IA is an ultra high response speed, high temperature, high precision, fully calibrated absolute humidity sensor. Modern manufacturing technology ensures high reliability and excellent long-term stability. The sensor includes a humidity sensor and a high-performance 24bitAD integrated CMOS microprocessor. The product has the advantages of excellent quality, super fast response, strong anti-interference ability and high cost performance. The machine is highly integrated and suitable for high quality and large-scale production requirements. It is an ideal choice for users and is convenient for OEM applications of cooperative manufacturers.

AHS01IA communication mode uses the I2C digital communication mode, the ultra small volume and the very low power consumption, making it the best choice for all kinds of applications and even the most harsh applications. The AHS01IA operating voltage is 3.3V. This device can provide low cost and low power advantage for all kinds of common application scenes. The absolute sensor is calibrated in a high precision constant temperature and constant humidity chamber to directly output the true value of the detected ambient humidity. The user does not need to carry out the two processing of the signal again, and the exact humidity can be obtained. It reduces user cost and facilitates the two development of users.
