SHT10 - Sensirion

SHT10 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the SHT10?
  The recommended power-up sequence is to apply VCC first, followed by a delay of at least 15 ms, and then apply the clock signal. This ensures proper initialization of the device.
• How do I handle the SHT10's open-drain output?
  The SHT10's output is open-drain, which means it can only sink current, not source it. To use the output, you need to add a pull-up resistor to a voltage source, such as VCC.
• What is the maximum cable length for the SHT10's digital interface?
  The maximum cable length for the SHT10's digital interface is approximately 10 meters (33 feet). Exceeding this length may result in signal degradation or errors.
• How do I convert the SHT10's humidity output to a relative humidity value?
  The SHT10 outputs a digital value representing the humidity measurement. To convert this value to a relative humidity (RH) value, use the formula: RH = -42.22 + 241.4 * (output value / 2^14).
• What is the SHT10's temperature accuracy, and how is it specified?
  The SHT10's temperature accuracy is specified as ±0.4°C (±0.72°F) at 25°C (77°F). This accuracy is valid for the entire operating temperature range of -40°C to 123.8°C (-40°F to 250°F).
