  • Forum Post: Re: Temperature sensor-TMP411 - Remote temperature meaurement

    Matt Hann
    Srvatsa, To be able to better assist with this issue it will be very helpful for you to post a read of the status and remote temperature registers as this will indicate which fault it tripping the ALERT pin. Also, I would highly recommend lowering your series resistance to no larger than 100 ohms and...

  • Forum Post: TMP102, ALERT pin pullup

    Lubos
    Hello, I've got TMP102 breakout PCB where ALARM pin is left unconnected (no pullup). I'm not going to use ALERT pin anyway, but does it any impact on communication via TWI bus? I've tried to communicate with the TMP102, but without any response. So, I'm trying to find where can be...

    Lukasz Baranski58559
    Hi Matt, I have a problem with TMP102 sensor. Specifically, the ALERT signal. After reading the entire directory SBOS397B note, I would like to set the TMP102 to work as follows. Example 1: We would like to receive the signal on pin ALERT . Tmax = 29 Tmin = 26 (Temperature measurements at the next...

  • Forum Post: TMP112 Alert pin to ground

    Sergio62851
    Hello Will the TMP112 work if the ALERT pin is connected to ground, GND? I'm not planning on using the alert function, I just want to read temperature. Thank you, Sergio

    Ian Williams
    Hello Sanjat, When the TMP112 is in Interrupt mode (TM=1), the interrupt becomes active in a cyclical fashion as shown in Figure 13 below and as described in the section HIGH- AND LOW-LIMIT REGISTERS . In order for an interrupt to occur, the part must first read a temperature equal to or greater...

    Anatoly, The official spec from NXP states that after receiving the 0x04 or 0x06 command, "all devices designed to respond to the general call address will reset and take in the programmable part of their address." This means that the address present on the hardware pins of the device will...

  • Forum Post: Re: TMP102 Electrical Characteristics and Clocking

    Chris Featherstone
    David, SDA and ALERT will be at the rail voltage when they are high (logic 1). The reason is because SDA and ALERT are open collectors and the pull up resistors will pull the output to the rail voltage in the case of logic 1 (high). The TMP102 will always be the slave device while the microprocessor...
