WBA-TH1M

Module Specifications

Very compact PCB size: 0.5" x 1.0"
Optimum circuit layout for versatility:

• 1uF bypass cap
• 10k pullup on data line
• 10k pull down on clock line (see FAQ #23 and note below about I2C)
• 330ohm inline protection resistors for clock and data lines

4 pin 0.100" header location for VCC, Clock, Data, and GND

Solder pads for wire attachment

Rear side pinout label

Supplied with a 4 pin right angle and straight header (unsoldered) to allow user versatility. This allows for top, bottom, and vertical mounting.

Manufactured to IPC-610 specifications

Functionally Tested

Warrantied, 30 day exchange

• 2 sensors: humidity and temperature
• Humidity:
  • Range: 0-100% RH
  • Accuracy: +/- 3% RH
• Temperature:
  • Range: -40°F (-40°C) to 254.9°F (123.8°C)
  • Accuracy: +/- 0.4°C @ 25 °C
• Precise dewpoint calculation possible
• Calibrated & digital output using a simple 2-wire interface
  • Similar to I2C, but I2C cannot be used with the SHT11.
  • The SHT11 sensor can share clock and data lines with an I2C bus and will not be adversely affected.
  • NOTE: When the WBA-TH1M module is connected in a manner that will share an I2C bus, the pulldown resistor on the SCK line must be removed so that the module will not prohibit proper I2C communications for I2C devices.
• Fast response time < 8 seconds
• Low power consumption (typ. 30 µW)
• Long term stability
