HTPA thermal infrared temperature measurement module


Can be used for non-contact temperature measurement.

Parameters

  • Power supply voltage (DC): 3.3V
  • Current consumption: 5.5(±1.0)mA
  • Clock frequency (sensor): 5(±3)MHz
  • Ambient temperature range: -20 ~ 85℃
  • Target temperature range: -20 ~ >1000°C
  • Frame rate (full frame): 2 ~ 27hz
  • Frame rate (quarter frame): 8 ~ 110hz
  • Noise equivalent temperature difference (best optics): 140mK@1Hz
  • Communication method: I2C

Instructions

MaixPy has implemented htpa in modules (you need to enable the module when the firmware is compiled to be available).

  • Import and create htpa
from machine import I2C
from modules import htpa
dev = htpa(i2c=I2C.I2C0, scl_pin=7, sda_pin=6, i2c_freq=1000000)
  • Get the temperature of all points in the detection range
temperature = dev.temperature()

API details refer to modules.htpa

Routine

  • Draw temperature distribution graph on LCD: htpa demo
