AM1011A — Upgraded Humidity & Temperature Sensor

AM1011A is an upgraded sensor module that includes a dedicated ASIC, a high-performance silicon-based capacitive humidity sensor and an on-chip temperature sensor. It provides an analog voltage output (0–3 V). Compared with the previous generation, AM1011A offers improved stability in high-temperature/high-humidity environments, better accuracy, faster response, and a wider measurement range. Each unit is factory calibrated and tested for reliable mass deployment.
