Sensing range of Wireless Temperature sensor

Hi,
In wireless temperature sensor, I am using HIH9130 sensor with which we are monitoring the wireless sensor data. But I need to know for what range this sensor can sense environment value. As I going to use this sensor in the Tool production area which is around 70 yards.

Will be looking out for your suggestions here

I looked for datasheet 'hih9130' and it no longer exists on Honeywell's website, though there are several versions, perhaps there's a replacement ?
Please post your device's full part number and a link to the datasheet.
What you want to know will be there, unlike the frezing rain coating everything here..

My 'gut' feeling is that this is a 'local' (PCB) sensor, designed for the HVAC industry, maybe even in home dehumidifers.
As for 'long distance' temperature reading, I'd 'modify' one of the handheld IR 'guns' that you can buy for $20 CDN.

The posted question doesn't make any sense.
The 'temperature sensor' he links to is a long range wireless temperature
and humidity sensor. It uses the Mesh wireless network. It incorporates
an HiH9130, as it's sensing element.
The HiH9130, is a single IC humidity sensor available in I2C or SPI versions.

The sensor he is pointing to, has a range that it totally dependant on the
environment itself, what the other device is, and the antennae used. With a
suitable directional Yagi antenna, you can use devices like that at mile
distances. However if (for example) you are trying to work through a welding booth, then you can have problems over only a few yards.

You'd need to do a RF site survey, and then work out the optimal locations
for the antennae. It's not a question that can have it's answer 'guessed' at.

The range can also be changed by adding repeaters.

Yes, but the 8130 replaces it.

Thinking about it I wonder if he is trying to ask the infra read 'range' of the sensor (as Temtronic says, like non contact IR sensors). This is not a sensor of this type. It is a environmental sensor. Reads the temperature 'at' the sensor.

well I think I know what he wants..after going to the the 'light blue' link..., maybe.
Yes it'd communicate over the 70 yard distance (they say 'miles') but he wants to know how close the device needs to be to read the temperature of the target.
I couldn't find anything in the online manual to suggest how close the device has to be to the target though. TONS of info about setting up the network NOTHING about actual installation.
I'm guessing he want to 'point' the device at a machine, and read the machine's temperature, then transmit that information to some 'host'. We really need more details. I can 'see' having the device on a post, pointing at a 'machine'. Say it's looking at a motor. If the motor gets 'hot', the host then sounds an alarm ??

yeesh.. I download the datasheet for the 8130, that's a joke...NO info about the sensor 'range' (though I assume local) and NO I2C info !! I finally found another PDF describing the 'command/access' info...something I'd assume was in the PRODUCT datasheet....
sigh...

Exactly what I decided.
The sensor in this is an environmental sensor, not a radiant IR sensor.
So he needs to too 'look elsewhere' if he does want sensing like this.
I repeat my comment though about needing to do an RF survey to
get any idea of the communication range. Things like a welding booth, or
an RF heating system 'wreak havoc' with RF communications, (as do metal
walls or machines in the path).
