Introduction

DLP-TH1C is a USB-based module for acquiring temperature, humidity, pressure, sound, tilt, vibration, and light data. A basic host application and its source code project (Visual Studio, Visual C++) are included with the DLP-TH1C to demonstrate host communication via a Virtual COM Port (VCP). The host application can access all DLP-TH1C functions through single-byte commands. The DLP-TH1C uses a fully calibrated temperature, relative humidity, and pressure sensor. The calibration coefficients are permanently stored within the sensor and cannot be modified, making the module fully interchangeable with any other DLP-TH1C. The tilt sensor (accelerometer) offers four user-selectable ranges: 2G, 4G, 8G, and 16G. This sensor reports X, Y, and Z axis tilt as influenced by Earth's gravity. Vibration frequency can be measured over a range of 25–2500Hz (with 20Hz resolution). The reported vibration data points include the fundamental frequency (maximum peak level) along with the five next-highest peaks that may exist above or below the fundamental. Ambient light entering through the opening in the DLP-TH1C plastic enclosure is measured by an onboard light sensor. An 8-bit byte is returned representing the ambient light level (range 0–255) and reports the light level to the host application. Sound is measured by an onboard microphone and preamplifier. Sound frequency and amplitude can be measured over a range of 25Hz–10KHz (with 78Hz resolution). The reported sound data points include the fundamental frequency (maximum peak level) along with the five next-highest peaks that may exist above or below the fundamental. An additional measurement of broadband ambient sound level is also provided. No external power supply is required. All power (50mA at approximately 5V) is drawn from the USB port via the included 6-foot USB cable.
