  • Forum Post: LMP91000 sensor interface

    Vic McCarn Vic McCarn
    I have a chemical gas sensor and I need to build an electronic interface for it. I have the LMP91000 eval board. At one time I thought I'd need a simple potentiostat, which the LMP91000 would work well for. However, as I have progressed I've found the best way to operate the sensor is as a resistive...

    Joel Wong Joel Wong
    Hi, I've been using the LMP91000 to test if it can detect various chemicals. However, when I save the data to file, there are no units for the data and it doesn't seem to correlate with the voltage that is shown on the graph vs the resistor chosen on the gui. Any help is appreciated. Thank...

    Darren Valantine Darren Valantine
    I am trying to interface the LMP 91000 evaluation board with a Microchip 16F877 microcontoller. I have tried the built-in I2C functions but can not get an Ack for the 9th bit. Using a scope the SDA line stays around 1.8V for the Ack bit. I have also tried programming the MENB, SDA and SCL directly...

    Hello, I am using lmp91000 with different type of sensors having same characteristics i.e. the output voltage should increase as the increase in that particular gas, but i am getting opposite responses with some gases it is increasing and with some gases it is decreasing with the same settings of the...

  • Forum Post: LMP91000 with 4-lead fuel cells

    Andre Araujo Andre Araujo
    Hello everyone, I recently learned about the LMP91000 AFE and was excited to use it in my application. However, I use 4-lead fuel cells from City Technology. I was wondering if anyone has found a workaround to interface 4-lead sensors with LMP91000. If it's not possible, to use LMP91000,...
