Sensebender Micro
-
Received my Micros today. Luckily there was no custom and a lot of pins to solder. Can't wait to solder them on wednesday on work and test them.
Is there any instruction how to solder everything? On which side the radio module needs to be soldered.

I hope this question has not been answered already and I did not miss the answer. I was thinking about connecting a motion sensor to this and was hoping that one of the digital pins supports an interrupt. Is there an interrupt available?

I'm planning to do the same thing.
i ordered my 5v step up regulators to support the PIR sensor.
although I hope adding the motion isnt going to kill the batteries. -

I have so far had no problems running my PIR sensors at 3.3v with the following hack.http://techgurka.blogspot.com/2013/05/cheap-pyroelectric-infrared-pir-motion.html
You can not do this with all PIR Sensors from what I understand, but one of the ones listed in the MySensors store is what I've been using. Go down to the bottom of the article.

wow.. nice.. thanks for the info! I will give this a go asap.

Are there any recommendations for a low power temperature, humidity sensor regarding the update cycle.
Currently I plan to wake up the sensor each 10 minutes instead of each 1 minute to update the values. This should increase the duration of the battery. A complete update of all values if performed each 30 minutes as usual.
-
I would probably choose 5 minutes interval instead.. I have updated the sensebendermicro sketch tonight (just waiting for @hek to approve it). so it holds of on the transmissions a bit. Now the temperature needs to change more than 0.5 degrees from the previous transmitted value. OR
humidity needs to change more than 0.5, measured with a moving average. OR
30 minutes since last transmission. -
I found that when I power the micro from 2 batteries I get the following error:
T: 23.21 H: 50 send: 104-104-0-0 s=1,c=1,t=0,pt=7,l=5,st=fail:23.2 send: 104-104-0-0 s=2,c=1,t=1,pt=2,l=2,st=fail:50This does not happen when I power it from the FTDI programmer.
Does anybody have any ideas?
The batteries have a voltage of 3.25VI did not have this issues with my arduino nano sensors. and i did use the same radio modules.
When I check the modules they seem to be real nrf24l01+ modules:
STATUS = 0x0e RX_DR=0 TX_DS=0 MAX_RT=0 RX_P_NO=7 TX_FULL=0 RX_ADDR_P0-1 x00 = 0xe7e7e7e7e7 0xf0f0f0f0d2 RX_ADDR_P2-5 x00 = 0xc3 0xc4 0xc5 0xc6 TX_ADDR = 0xe7e7e7e7e7 RX_PW_P0-6 x00 = 0x00 0x20 0x00 0x00 0x00 0x00 EN_AA = 0x3f EN_RXADDR x00 = 0x03 RF_CH = 0x4c RF_SETUP x00 = 0x07 CONFIG = 0x0f DYNPD/FEATURE x00 = 0x00 0x00 Data Rate = 1MBPS Model = nRF24L01+ CRC Length = 16 bits PA Power = PA_HIGH -
I have a batch of 5 sensebender and actually I build 3 and one of them doesn't work properly. Lot of st:fail when I put my finger on the board it works better so I try to make all solder one more time but it's not ok. I try with few radios and same radios work well on the others sensbender.
Any idea or way to exchange with Itead ?
