analog sensor 0-5V COL

[athxp]

TMP36 has an output of 10mv per degree. with 25 degrees it returns 750m. the excursion should be -40 to +125 degrees, with an increase of 10mV per degree. Can COL handle it?


DHTM-02S should instead have a 0-5 V output for temperature (-20 +80) and humidity (0-100% RH)

i have checked TMP36 output voltage range is 0-1.8V, so it can't use for COL.
DHTM-02S if output 0-5v, this can be used.

ok thanks, I'll do some tests

I tried the DHTM-02s sensor which outputs an analog 0-5 V signal for temperature and humidity.

without connecting to COL I checked the output value by heating it and it reaches over 4.5V.
unfortunately connecting it to COL the value drops to about 1.6V
at room temperature the sensor returns about 2.3V, connecting it to COL they become 0.6V

am I wrong something?

take a photo , how you connect with wires.
