Vaisala HMM105 Digital Humidity Module for Environmental Chambers
The Vaisala HMM105 provides reliable humidity measurement for integration into environmental chambers, incubators and OEM equipment.
- 0–100% RH measurement range
- I2C output for relative humidity or dew point
- Detachable 12 mm probe with 300 mm flexible cable
- Probe withstands +180 °C continuously and +200 °C temporarily
Vaisala HMM105 Digital Humidity Module
The Vaisala HUMICAP® HMM105 is an open-frame module for equipment manufacturers who need dependable humidity measurement inside an environmental chamber or incubator. Its separate probe assembly allows the sensing point to be placed inside the chamber while the circuit board remains in a suitable protected location.
The module communicates directly with the host controller through an I2C interface. The controller can read relative humidity or dew point, monitor device status, change operating parameters and carry out measurement adjustments without adding an external transmitter.
Designed for Chamber and Incubator Integration
The HMM105 combines a compact circuit board with a detachable probe head, M10 × 1 mounting thread and 300 mm flexible cable. This arrangement simplifies installation in equipment where available space, service access and the separation of electronics from the measurement area must be considered.
Full temperature compensation supports reliable humidity measurement across demanding chamber conditions. The probe can operate continuously at temperatures up to +180 °C and tolerate short-term exposure up to +200 °C, making it suitable for equipment that includes high-temperature cycles or heat sterilisation. The component board must remain within its specified operating-temperature range.

HMM100, HMM105 or HMM170?
All three modules are intended for integration into environmental chambers or OEM equipment. The correct choice depends mainly on the required electrical interface, chamber conditions and maintenance functions.

Quick selection: choose HMM100 when the chamber controller needs a conventional analog signal. Choose HMM105 when direct I2C communication and a compact detachable probe are required. Choose HMM170 for new demanding designs that need better accuracy, Modbus RTU, several analog outputs, longer probe cables or active condensation protection.
Integration Information to Confirm
Before ordering the HMM105, confirm the chamber temperature and humidity range, controller supply voltage, I2C implementation, preferred output parameter, probe mounting position, electronics-board location and exposure during sterilisation or cleaning cycles.
The HMM105 is a component module intended for integration by an equipment manufacturer or system designer. The finished equipment should provide suitable mechanical protection, power, wiring, grounding and electromagnetic-compatibility arrangements.
