WEBVTT 1 00:00:02.400 --> 00:00:08.820 We have a big ongoing project with the largest egg manufacturer in the Northern Europe called Balticovo. 2 00:00:08.820 --> 00:00:13.840 Together with them we managed to understand that there are four most important parameters 3 00:00:13.840 --> 00:00:18.260 Which are directly related to the business parameters of egg industry 4 00:00:20.560 --> 00:00:28.000 These four parameters are temperature, relative humidity, CO2 concentration and ammonia concentration. Why? 5 00:00:28.860 --> 00:00:34.719 Like for us, for humans the temperature and the relative humidity are the main parameters which 6 00:00:34.720 --> 00:00:38.240 Are directly related to our physiology 7 00:00:38.240 --> 00:00:42.620 and the mood, and everything – our productivity. The same statement is correct 8 00:00:42.620 --> 00:00:47.880 for the egg-laying hens. And I guess, also for the broilers in the poultry industry. 9 00:00:48.480 --> 00:00:55.860 CO2 concentration. Although birds can withstand much higher CO2 or carbon dioxide levels, 10 00:00:55.860 --> 00:01:02.480 But still there are limits, and CO2 concentration is a very good indicator of the ventilation system of the barn. 11 00:01:03.520 --> 00:01:11.940 Ammonia is the most challenging part from the design point of view, because it's not only important to be able to measure 12 00:01:11.940 --> 00:01:16.100 ammonia concentration. But ammonia together with the relative humidity 13 00:01:16.100 --> 00:01:21.360 makes very, very chemically harsh conditions, very corrosive environment, 14 00:01:21.360 --> 00:01:25.380 which is a challenge from the design point of view, because you have to seal 15 00:01:25.380 --> 00:01:30.000 all the electronic components so that they are not influenced and they are not corroding 16 00:01:30.000 --> 00:01:31.580 during the measurement process. 17 00:01:31.580 --> 00:01:37.860 It is well known that even low ammonia levels, say 20 or 25 ppms 18 00:01:37.860 --> 00:01:42.240 can be very disastrous for the for the business. 19 00:01:42.480 --> 00:01:48.120 Because ammonia influences the respiratory system of the hens, 20 00:01:48.180 --> 00:01:52.920 the quality of meat goes down, and also because of the high ammonia concentration 21 00:01:52.920 --> 00:01:55.200 the productivity of eggs goes down. 22 00:01:55.200 --> 00:02:00.320 Which means that you have to feed them much more to maintain the same productivity level, 23 00:02:00.320 --> 00:02:03.980 Which of course is a drawback from the business point of view. 24 00:02:05.180 --> 00:02:07.100 In order to address these problems, 25 00:02:07.100 --> 00:02:12.520 We designed a small line of sensors which are suitable for the poultry industry, 26 00:02:12.520 --> 00:02:15.060 and i'll try to explain shortly 27 00:02:15.760 --> 00:02:19.040 what are the main benefits of those sensors. 28 00:02:19.520 --> 00:02:25.380 The simplest one is temperature sensor. It measures temperature, it sends away the data via radio, 29 00:02:25.440 --> 00:02:28.060 But the important feature is that the 30 00:02:28.080 --> 00:02:33.440 casing is very robust. It has the Ingress Protection class IP68. 31 00:02:33.440 --> 00:02:35.180 This is good in our opinion 32 00:02:36.380 --> 00:02:39.680 The measurement of relative humidity is more challenging, 33 00:02:39.920 --> 00:02:44.100 because typically relative humidity sensors, they are 34 00:02:44.100 --> 00:02:47.340 not resistant to chemical contamination, 35 00:02:47.400 --> 00:02:52.720 which is a priori present in the bird barns – because the main contaminant is 36 00:02:52.720 --> 00:02:56.580 ammonia, of course. Most of the sensors are drifting in time. 37 00:02:56.640 --> 00:03:03.180 Our sensor is specifically selected to address this problem – to be stable in the ammonia atmosphere. 38 00:03:03.440 --> 00:03:08.880 And you have a relative humidity sensor, which can be used in ammonia atmosphere. 39 00:03:08.880 --> 00:03:13.380 The next one is the CO2 sensor. The main feature is that it uses 40 00:03:14.060 --> 00:03:17.260 a non-dispersive infrared sensor in it, 41 00:03:17.460 --> 00:03:22.600 which basically means that it is a spectrometer – with all of the consequences and benefits. 42 00:03:22.600 --> 00:03:25.740 So it is very sensitive 43 00:03:25.920 --> 00:03:29.140 to the CO2, but not sensitive to other gases, 44 00:03:29.560 --> 00:03:36.460 completely no cross contamination effect, and it has a wide range, and also acceptable accuracy. 45 00:03:37.140 --> 00:03:41.360 And the last one is ammonia or NH3 sensor. 46 00:03:41.360 --> 00:03:48.080 It's an electrochemical one, and the main feature that we put a lot of effort into it, in order to 47 00:03:48.240 --> 00:03:53.660 compensate for the temperature and relative humidity effects. 48 00:03:54.160 --> 00:03:57.620 Using these Aranet sensors, we managed to do 49 00:03:57.620 --> 00:04:05.160 the installation of almost 200 sensors in less than two days in real egg industry barn. 50 00:04:05.560 --> 00:04:12.360 The first results are very promising, because we already managed to find the most effective, so to speak, spots – 51 00:04:12.360 --> 00:04:16.960 the most problematic spots of the barn, of the climate of hens, 52 00:04:16.960 --> 00:04:20.960 and our partner, they are already trying to optimize 53 00:04:21.000 --> 00:04:24.200 ventilation system in order to improve their parameters 54 00:04:24.200 --> 00:04:30.380 We are continuing the work on our poultry sensor line, and currently in the pipeline we have 55 00:04:30.380 --> 00:04:35.520 a CO or carbon monoxide sensor, and also a hydrogen sulfide sensor, 56 00:04:35.520 --> 00:04:40.420 which also are important contamination gases in the bird industry. 57 00:05:22.000 --> 00:05:26.400 We are in the initial stage of our collaboration project with Balticovo. 58 00:05:26.400 --> 00:05:34.560 The results are promising and we believe that we will manage to provide the guidelines which will allow our partners to 59 00:05:34.640 --> 00:05:40.020 significantly improve the parameters which are important in their business.
