Receiving only 0s for SEN0177

I am using an Arduino Uno that is connected to a PM2.5 adaptor that is connected to the PM sensor. I have tried using software serial and hardware serial, but the serial monitor still reads 0 on PM1.0, 2.5, and 10.

2019-10-01 18:46:41 i'm using a separate power supply for the adaptor board/SEN0177
it is set for 5V and it seems to cycle thru a current consumption of 50 -70mA

what else do you need me to check ?
thanks for your time anonymous

2019-09-29 19:25:16 Hi,
i have the PM2.5 adapter V2.0 board connected to the SEN0177.
i use software serial (RX: 10, TX: 11)
code is V3.1, march 25 2016
thanks for your time anonymous

2019-09-28 23:49:25 can you tell what you did to get it to run?
i have the same problem using the SEN0177 and an arduino UNO, all i get from the sensor is 0's
tried another board, checked connections again and again etc ...
but nothing works it only returns 0's anonymous

2018-02-09 23:39:49 If you use hardware serial, how do you display the reading, you can't use serial monitor to display the outputs. robert.chen

2018-02-09 01:24:01 How do you connect the sensor? can you show a picture of the wiring? robert.chen
