BME280 consumption

Projects Programming
1

Hello.

I am building ultra low consumption sensor network. However, my BME280 Sensor consume 0.2 mA in sleep mode, when it should consume 0.2 uA.

I think I use sleep mode correctly, because if I don't use sleep mode, current is 0.8mA so sleep mode works.

This happens to all my BME280 sensors, but they all bought from ebay for the lowest price.

So If there are mistake in my code or these all 4 sensors are bad?

#include <RF24_config.h>
#include <SPI.h>
#include <RF24.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_BME280.h>
#include <avr/sleep.h>
#include <avr/wdt.h>
#include <LowPower.h>

#define BME_CS 10
Adafruit_BME280 bme(BME_CS);


void setup(void) {
  bme.begin();
}


struct dataStruct {
  
  float temp;

} Data;

void measure() {
  bme.write8(0xF4,B01111100); //last 00 enable sleep mode.
  Data.temp=bme.readTemperature();
  delay(10);
}

void loop(void) {
    measure();
    LowPower.powerDown(SLEEP_1S, ADC_OFF, BOD_OFF);
  }

P.S I bought 5 NRF's also from ebay and 4 of them consumed 1000 times more current in sleep mode...
