Digital Humidity and Temperature Module for Cost-Efficient Measurement
The HTM502 digital humidity and temperature module combines ease of implementation, accuracy and reliability to meet current and future market requirements. The easy interchangeability and fast integration via I²C allow a quick project realisation.
HTM502 – Digital humidity and temperature module
High measurement accuracy, robust design
The HTM502 sensor module measures humidity and temperature with an accuracy of ±2.0 % RH and ±0.3 °C and can be used in applications from 5 °C to 60 °C. The robust housing makes the module particularly suitable for price-sensitive HVAC applications, but also for industrial applications. The robust housing gives the module high mechanical stability and ensures easy handling by preventing accidental contact with the sensor element. The integrated E+E sensor coating protects the sensor element from dirt and corrosion, improving measurement performance and long-term stability in harsh and demanding environments.
Quick integration via I²C
The I²C interface allows easy integration of the humidity and temperature module, enabling projects to be implemented quickly. The HTM502 offers two measurement modes (single-shot or periodic measurement mode) and supports communication speeds up to 1000 kHz. Thanks to the low supply voltage of 2.35 – 3.60 V and the low power consumption, the module is also suitable for low-power applications.
Easy mounting and replacement
The design of the HTM502 allows easy mounting without additional implementation effort or soldering. The 4-pin connector plug allows quick replacement of the sensor module in the field.
