Micro/sys Releases Environmental Sensor Board for StackableUSB™

Montrose, CA... As embedded systems take a pivotal role in our nation’s "green" movement aimed at conserving energy, Micro/sys’ I2C1610 provides system designers a powerful tool in a I2C device which enables an embedded system to monitor four different environmental criteria. Incorporating highly-integrated sensors onto a compact 1.85" x 1.74" form factor, the I2C1610 is able to measure temperature, light, humidity, and atmospheric pressure, either inside or outside the system enclosure. The Host computer receives the sensor status via the StackableUSB connector, thereby enabling the embedded system to adjust its performance to match environmental needs. OEMs will benefit by using the I2C1610 board as a simple, low-power, cost-effective solution for making embedded systems environmentally aware and energy efficient.

Using intelligent sensors that are smaller than thumbnails, the I2C1610 easily incorporates sensors from four leading environmental sensor manufacturers on a board that is one-quarter the size of the 104™ Form Factor. The Rohm Ambient Light Sensor provides a high-resolution sensing range (1 to 65535 lx) for detecting the changes in ambient light with a spectral responsibility of 400nm to 850nm, the frequency of visible light. For the robust, reliable humidity calculations, the I2C1610 employs the Honeywell HIH Series Humidity Sensor which detects sensitivities from 0 to 100% RH with an accuracy of ±3.5% RH. Next, the Texas Instrument Digital Temperature Sensor allows access to four user-selectable resolutions from 9-bit to 12-Bit with an accuracy of ±0.5° C. The fourth sensor, the Infineon Absolute Atmospheric Pressure Sensor, enables the I2C1610 to accurately gauge input pressure from 40 to 115 kPa and output voltage from 0.1 to 4.85V with a sensitivity of 53.3mV/kPa. With this four-punch combination of features, the I2C1610 can accurately measure and report the environmental conditions of most OEM systems.

In addition to sensing the environmental surroundings, the I2C1610 was designed and manufactured with other environmental advantages in mind. Requiring only 10mA of power, the I2C1610 can be operated on a 9V battery for remote monitoring, eliminating the need for excessive wiring and cabling at the measurement site. The I2C1610 is a RoHS compliant board on one of the smallest stacking form factors on the market, measuring a mere 1.85" 1.74"— which conserves and reduces the PCB materials used in manufacturing this product.

The basic I2C1610 starts at $150 in single quantity. Significant OEM discounts are available on all boards. Contact Technical Sales Dept., Micro/sys, Inc., 3730 Park Place, Montrose, CA 91020, phone (818) 244-4600, FAX (818) 244-4246, email:, URL:
