temperature

I am developing a project where I use two 18650 batteries in series as a buffer in case the primary energy source (electricity from the home network) is missing. I want to integrate an NTC sensor to monitor the temperature of the batteries, so as to isolate the batteries in case their...

I’m developing a Modbus RTU architecture. The master of this architecture is my Beagebone Black , which I want to connect via RS-485 serial communication to my sensors. Since I’m using RS-485 converters (RS-485 Converter) which need a UART input as far as I understand, I was looking for sensors...

Hello guys. I'm using an efr32bg22 Bluetooth module and would like to read a thermistor with it! I've never used a thermistor. Reading a little about the subject, it seems a little complicated to me. There are some formulas for obtaining a conversion but apparently the best way is to use a...

Hello, I'm planning to measure temperature with PT100 using 4 wires. So I need stable current source or some nice IC with that, ADC and maybe filters (sinc for 50Hz or just downpass). I have found MAX31865. It has nice resolution but poor accuracy ± 0.5 ° C (?). Is there any better chip for my...

Hi all I have to monitor the temperature of a surface for several hours per day. The circuit will be battery powered. I already have a LM358 op-amp and a TMP36 sensor at home. I thought 4x AA NiMh batteries (1.2V) are ok. I just want an LED ON when the temp is over 50 degrees Celsius and...

Hello, This question might seem basic but I would like to state it. I would like to calculate the operating/Rise temperature of the ferrite core of an inductor. I am modelling my own bobbins for the core so I need to decide on the material/filament to use for 3D printing which can take the...

Hello evryone, I start studying Eletrical and computer engineering and I want to learn thermocouple type k,j etc, however I've been searching and I can find to measure temperatures is using water bath 0° in cold junction so voltage will be the same as thermocouple tables on google, however...

Hello folks, I have an old Omega CN-9121 PID Controller and a 105Watts 115V Fibre heater mantle with an inbuilt K-type CHromel-Alumel temperature thermocouple also attached into it. I plan to use the PID controller to control the temperature of the heater. Looking at the manual below: Manual...

Hello everyone, I'm trying to find out the model of the two chips on a temperature/humidity sensor. As you can see the surface of the chips have partially melted. I think I found the model of one of them (the long-one with 14 pin): ICM7556. I found this link to a datasheet But I can't find...
