Hi friends.... I have a King Pigeon S264 temperature & humidity. I bring the device to China and I have problems for conect phone with the device. Anyone can help me, I from Chile and here there isn´t any place for my Doubt. Is very important for me because the device is very expensive and I dont chance to return it.

Hi,

Wanted help regarding the limits of configuration of Si7210-B-04-IV(R)

We want to have the configuration of the Bop(operating point) and Brp(release point) to be 4.10mT and 2.45mT respectively, with hysteresis being 1.65mT(= 4.10mT - 2.45mT). Is it possible to configure this sensor for the above defined values using I2C? Because the datasheet says the default Bop and Brp for this Si7210-B-04-IV(R) sensor are ±1.1 mT and ±0.2 mT respectively.

What is the maximum and minimum values to which Bop(operating point), Brp(release point) and Hysteresis be configured to?

And is the scale of measurement configurable to ±200mT as the default scale is also mentioned as ±20mT?

Please let us know what is the resolution with which we can measure the magnetic field in ±200mT scale.

 

I have read the datasheet, but it sounds a little confusing. So asking here for confirmation.

 

Thanks,

Tejas Kulakarni

Hi everyone,

I am trying to simulate the field of view of the si115x sensor when I use a lens in front of it. However, I don't know at what depth the IR photodiodes are buried in the clear DFN package. I didn't find this data anywhere.

A little help would be really appreciated.

Cheers

Hi

Where I can find sample code for the sensor?

Thanks

Hello everyone,

I am currently trying to use the Si1153 as a proximity sensor on Arduino. I used the library at https://github.com/PureEngineering/PUREmodules/tree/master/Arduino/Si1153. The whole configuration works very well, except about measurement timings. On the one hand, MEASRATE_H and MEASRATE_L have no influence at all on the measurement period. On the other hand, the MEASCOUNT_x register gives me only half the period I expected. I attached the library .cpp and .h. Here is my code :

#include "Si1153.h"

#define pinInterrupt 2

Si1153 si1153;

void setup() {

	delay(100);

	Wire.begin();
	Serial.begin(115200);
	Serial.println("Demarrage");

	pinMode(pinInterrupt, INPUT_PULLUP);
	
	//Ne pas utiliser param_set at IRQ_enable est directement accessible en I2C
	si1153.write_byte(Si1153::DEVICE_ADDRESS, Si1153::IRQ_ENABLE, 0B00111111); //Active les interruptions des 6 canaux

	//These three values are used by	MEASCONFIGx per channel to decide on the period per channel
	si1153.param_set(Si1153::MEASCOUNT_0,	16);
	si1153.param_set(Si1153::MEASCOUNT_1,	1);
	si1153.param_set(Si1153::MEASCOUNT_2,	1);
	si1153.param_set(Si1153::MEASRATE_H,	0);//Periode de mesure de base
	si1153.param_set(Si1153::MEASRATE_L,	5);
	si1153.param_set(Si1153::BURST,			0B00000000);//Burst ON
	si1153.param_set(Si1153::CHAN_LIST,		0B00000010); //Configure CHAN_LIST (Each bit represents a channel). This code enables channel 1.

	//Je n'utilise pas la fonction config_channel de la bibliotheque car elle ne fonctionne pas chez moi
	si1153.param_set(Si1153::ADCCONFIG_1,	0B01100010);
	si1153.param_set(Si1153::ADCSENS_1,		0B00000000);
	si1153.param_set(Si1153::ADCPOST_1,		0B00000000);
	si1153.param_set(Si1153::MEASCONFIG_1,	0B01000111);
	si1153.param_set(Si1153::LED1_A,		0x3F); //Regle le courant de toutes les LEDs
	si1153.param_set(Si1153::LED1_B,		0x3F);
	si1153.param_set(Si1153::LED2_A,		0x3F);
	si1153.param_set(Si1153::LED2_B,		0x3F);
	si1153.param_set(Si1153::LED3_A,		0x3F);
	si1153.param_set(Si1153::LED3_B,		0x3F);

	Serial.print(si1153.param_query(0x1A));
	Serial.print(" ");
	Serial.println(si1153.param_query(0x1B));
	
	si1153.send_command(Si1153::START);		 //Start the system
	
}

uint8_t data[2];

void loop() { //Limiter au strict nécessaire le traffic I2C pour réduire le bruit de la mesure
	
	while(digitalRead(pinInterrupt) == 1) {}
	si1153.read_byte(Si1153::DEVICE_ADDRESS, Si1153::IRQ_STATUS); //Necessaire pour acquiter l'interruption
	data[0] = si1153.read_byte(Si1153::DEVICE_ADDRESS, Si1153::HOSTOUT0);
	data[1] = si1153.read_byte(Si1153::DEVICE_ADDRESS, Si1153::HOSTOUT1);
	Serial.println(si1153.bytes_to_int(data, sizeof(data)));

}

If my understanding is correct, in this example I should get a measurement period of 800 us * 16 * 5 = 64ms. However, I only get aroud 6.8 ms on my oscilloscope.

I have been struggling with this issue for 2 days and can't find a way out. A little help would be really appreciated.

Best regards,

Valentin

Hello,

I have do a project on SI1133.I am using ALS photodiodes for light intensity detection.

My question is,

Is it possible to use SI1133 for RGB detection? based on the different wavelength ?

What kind of filter is the 940 nm passband filter? Is it a coating on top of the component or is it implemented inside?
The reason for the question is how sensible is the component for cleaning and handling. Have units that are reacting differently, reacting more to daylight than normal seams that the filter has been affected.

Hello Support Team,

Can you please share the test conditions,methods,results and reports of  Si1133-AA00-GM .

kindly support as soon as possible.

Hello,

Is it possible to use one of the Sillabs Humidity sensor in an space where there is 16 Bar of air pressure  ?

We have run the sensor for 3 days continuously and fetching the data in a fixed position.And we taken the sensor values with a LED .The  first value and the last value varies in the range of 1000.

Now I want to know ,what is the acceptable range to check the sensor is not degraded? 

I have a sensor which is not giving the sensor value(value is zero).But i was reading the partID of the sensor. It was return the value correctly(0x33).

Now the I2C communication of the sensor is good and the diode is not working.

Then how to know the diode has failed.Please elaborate.

Two Quantities of SI1102EK was purchase through mouser, we removed the battery for one unit and powered it using 3.7 volts battery. After certain duration the module stopped working and we found that the detection LED is always high and even after varying the provided pots for the threshold there was no change and the device is hung, please advice what has to be done to service the module to make it work. 

As I've read on this site, the Si1132 is NRND; the Si1133 is recommended to be used instead. But what about spectral response of the Si1133. Is it the same as of the Si1132 ?
