The HD35 series of wireless data loggers from Delta Ohm are available for a variety of parameters including: temperature; relative humidity; atmospheric and differential pressure; wind speed and direction; illuminance and UV radiance; solar radiation; CO; CO2; rain; and acceleration.

A version is also available for standard process sensors including PT100 and thermocouple temperature sensors, 4-20 mA and voltage signals.

All remote units have an internal memory of up to 74,000 readings and a secure robust wireless system with RF interference checking and automatic channel selection within the wireless operating band to ensure error-free transmission. Optional repeaters are available to extend the wireless range. Data stored in the loggers is retained until the memory is full, even after it has been sent to the base unit. The logger can then be programmed to stop logging or overwrite the older data.

IP67-rated outdoor versions of all data logger transmitters are also available.

Base units can handle up to 254 data loggers and versions are available with a USB PC interface and an integral GSM module (for SMS and email messaging), RS485 and Modbus outputs.

Additionally, a wireless alarm module is available controlled by the base station with two relay outputs for controlling alarm systems, etc.

Other features include an LCD option on all logger units, a lockable flange mount, user-friendly graphical software with many features including information of battery level, signal level and connection status of each logger.
