The Temperature/Relative Humidity Smart Sensor is designed to work with all Onset data loggers that accept smart sensors. All sensor parameters are stored inside the smart sensor, which automatically communicates configuration data information to the logger without any programming, calibration, or extensive user setup.
Measure soil moisture over a large volume of soil with the affordably-priced 10HS Soil Moisture Smart Sensor. This sensor integrates the field-proven 10HS Sensor and a 12-bit A/D. The 10cm probes measure soil moisture over a larger volume of soil which helps to average out any soil variability.
Measure soil water content with the affordably-priced EC-5 Soil Moisture Smart Sensor; this sensor integrates the field-proven ECH2O™ Sensor and a 12-bit A/D. The sensor’s two-tine design makes the sensor easy to install. Readings are provided directly in volumetric water content.
The Photosynthetic Light (PAR) Smart Sensor is intended to measure light intensity for the frequencies relevant for photosynthesis. This sensor has a measurement range of 0 to 2500 umol/m2/sec over wavelengths from 400 to 700 nm.
This Rain Gauge Smart Sensor measures rainfall with intensity up to 12.7 cm per hour with a resolution of 20 mm, and 1% accuracy for rainfall rates up to 0.2 mm/hour. The tipping bucket mechanism is mounted on a stainless steel shaft with brass bearings. This model includes a 2m cable.
The Wind Direction Smart Sensor is a research-grade plug-and-play sensor for measuring and logging wind data. It provides average wind direction for the measurement interval. This highly-durable wind vane has a drip overhang for anti-icing. Its shielded stainless-steel ball bearings and static-dissipating housing provide a long sensor long life. The sensor calculates a unit vector average of the wind direction, providing data directly in degrees.
The Wind Sensor Set includes Onset's research-grade plug-and-play Wind Speed Smart Sensor and the Wind Direction Smart Sensor. This combination provides average wind speed, highest three-second wind gust and average wind direction for the measurement interval. These durable sensors will provide many years of accurate and reliable performance.
The Solar Radiation Smart Sensor is a light sensor (silicon pyranometer) with a measurement range of 0 to 1280 W/m2 over a spectral range of 300 to 1100 nm. This sensor reports the average light intensity over a user-set set logging interval from a minimum of 1 second.
The Contact Closure Pulse Input Adaptor connects sensors with pulse outputs to loggers with smart-sensor inputs. This smart sensor is compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch-type of normally-open
The 12-bit 4-20 mA Input Adapter interfaces with any sensor providing a 4-20 mA signal to connect to smart sensor compatible data loggers. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries.
The Electronic Switch Pulse Input Adaptor connects sensors with pulse outputs to loggers with smart-sensor inputs. This Smart Sensor is compatible with electronic switch closures such as FET or open-collector outputs, or CMOS-level logic signals with a maximum input frequency of 120 Hz (120 pulses per second).
The 12-bit Voltage Input Adapter interfaces with sensors providing 0-5 VDC signals to act as a smart sensor with compatible data loggers. This adapter features both a non-switched input and a battery-saving switched input that extends the life of external batteries. It also provides a trigger signal for controlling power to attached external sensors, while offering digital filtering which improves measurement accuracy with 32 readings/sample.
The 12-bit FlexSmart Analog Input Module for use with the H22-001 Energy Logger handles two single-ended input channels with user-configurable ranges of 0 to 20mA DC or 0 to 20 V DC which is suitable for 2.5-, 5-, and 10-volt sensors.
