1.  product overview;

AHS01IA is an ultra-high-response, high-temperature, high-precision, fully calibrated water vapor sensor. The modern production process ensures high reliability and excellent long-term stability. The sensor includes a humidity sensing sensor connected to a high performance integrated 24-bit AD acquisition CMOS microprocessor. The high integration of the whole machine is very suitable for high-quality, large-scale production requirements, and is an good choice for users, which is convenient for OEM applications of cooperative manufacturers. AHS01IA operates is at 3.3V. This device provides low cost and low power consumption for a variety of common applications. The water vapor sensor is factory calibrated in a high-precision constant temperature and humidity chamber to directly output the detected ambient humidity. The real value, the user does not need to perform secondary processing of the signal, can obtain accurate humidity information, reduce the user's cost, and facilitate the secondary exploitation of the user.
