How to reduce the power consumption of the ATtiny?
I started so a little experiments with the ATtiny85 low power modes using the sketch of insidegadgets, achieving a power consumption of about 4.5uA in standby and of about 3mA during the led flash that […] […] in order to reduce the conflicts of having other motion sensors on the same band.
When to use sleep mode on the ATtiny?
[…] I always use sleep mode for the lowest power usage when not transmitting. It’s set to transmit about once every 6 minutes. There are several sleep mode routines for the ATmega processors, but the ATtiny needs entirely different registers set. I found good info on sleep mode, and good tutorials for the ATtiny at brownsofa.org and Inside Gadgets.
How much power does the attyni13a use in sleep mode?
In this case the ATtyni13A is up and running 24/7 and everything else is without the power, so the consumption of the rest of the circuit is 0A. ATtyni13A consumption is only 0.005mA (5µA) in a sleep mode.
How much power does the Arduino attiny13a use?
ATtyni13A consumption is only 0.005mA (5µA) in a sleep mode. As you can see, ATtyni13A is used only as a controller of 1 N-channel MOSFET, that is turning on/off 5V booster for the Arduino UNO plugged with standard USB cable. For the tests used in this post I have used LED to measure power consumption instead of MOSFET.
How to reduce sleep current in ATtiny digispark?
When using these modules in battery powered applications one often wants to reduce power consumption by using the sleep capabilities of the ATTiny85. The processor itself has low sleep current which can be further reduced by turning off functional pieces of the micro-controller.
How much power does the attiny85 Arduino use?
Right now it is using ~1.28mAh, it should be possible to get it much lower (I am using AA batteries as the power source). The ATtiny85 has its fuses set to run at 1MHZ, with BOD disabled.
Where does the power come from on the attiny85?
The ATtiny85 has its fuses set to run at 1MHZ, with BOD disabled. I am using this board to mount the CPU. I desoldered the power LED and the regulator, feeding power directly from the batteries to the 5V input. Nothing was connected to any other pins while measuring, just 5V and GND.
