my sensor is getting very hot even if i try it with 5v or 3.3 v. i also tried with 4.7k resistors on sda and scl but still no improvement....

hello @patty-victor i had same issue of sensor getting hot. i tried with both 3.3 and 5 v . also my ird and rd are not connected to ground. even...

i m using MAX30100 sensor from sunrobotics . i m connecting the circuit:- vin to 5v, sda scl to 5 v with 4.7k resistors and int ird and rd are...

i connected 1.8k resistor to vin and then to 5 v . now its not heating but its not working too.

when i changed the pull up from 5 to 3.3 the sensor doesnt work. the light glowing goes dim. and my sensor looks like this  i think it has...

and whenever i m trying to run the code it say intialize success but doesnt go ahead. it never enters the loop i guess. no readings are detected. not even...

hello @akshay-solanke my sensor doesn't work i guess with 3.3 v cause when i give 5v it starts blinking(acts like working) but with 3.3 it just lights up. and is...

@yashrastogi7 my sensor was getting heated way too much. what exactly is your sensor problem?

@yashrastogi7 1st use pullup and give 3.3 V only. And try to check the circuit again because some pins need to leave open (not connected to anything) IRD RD. and...
